Hello All,

I have just taken ownership of a BSA Bantam. (I think) The bike is completely in bits and i would like some expert help to get it on the road again.

This will be a project for me and my farther, I dont know much about the old bikes but want to get this rebuilt to original condition (Depending on cost)

I have the Frame, fuel tank and a few other parts but looking at pictures it’s hard to judge the age as the mudguards dont tally up with the frame and tank style.

The old number plate looks to still be there (UDD 904) I have phoned DVLA but they can't give me a year of 1st registration.

I guess the 1st question is how can i find out the year of the bike? From this i can then find the model and colour is should be? the frame number is all numbers and is hard to read. I know you all will have some great ideas and be able to help and i guess you will need some more information from me.

I will try and add the pic's that i have to help.

thank-you

Either full engine and frame numbers and or some photos should identify what you have got. If it's a D1 (125) then it's not uncommon to find a combination of engine/frame etc, sometimes with the later models too !

Thanks for the reply cornish, I'll try post some pics. 

Where can I find out the age once I have frame and engine number?

I will need to get more bits for it too. Any information on where the best place to sorce parts and paint will also be very helpful. (never attempted anything like this before so have hundreds of questions!) :-)

Welcome Bola! Please post some pics so we can see what's there. The Bantam club has a list of recommended suppliers for all manner of things that you might need, which you will get if you choose to join up. No pressure though! You can also ask any questions here, or search the forum to look for answers. That's what the forum is for, and no question is too silly.

When you have found your engine and frame numbers you can get a dating certificate from the club, which you can present to DVLA and get a registration number. Hopefully you can keep your original number, but not if it was transferred to another vehicle. It can be a complicated process depending on the history of the vehicle but lots of people here have been through it. Mine was very straightforward because i still had the original engine and frame. You might be lucky, but as Cornish said, you might have a replacement engine. This is not a problem as the dating goes by the age of the frame.

good luck with the bike! And have a nosey round at other member's restorations that are documented here, if you need some motivation and inspiration!

Great,  thanks. 

I can't add pis at the moment. (file exceeds allowed size) but will keep trying. The frame numbers I'm looking at are all numbers.

Looking at the date my bantam area of this site it seems I should have letters also. Can you point me in the correct area on the frame i should be looking? It looks to have a couple layers of pain so I might need to do some rubbing down to find it!

Frame numbers should be on the headstock, between the forks and the tank. But you did say it might not be a bantam, so that might explain why there are no letter? Could it be another small bike such as a Francis Barnett or a James? I haven't a clue how the frame numbers look on those. There is a problem with uploading big photos. Get them down to a small size, under 1000 kb should load i think. That's why i don't upload many pics, i am too lazy to resize them!

If its a Bantam, the frame number may also be on the nearside of the frame, just in front of the front engine mount. An early frame number has a couple of letters and a sequence of numbers.

The engine number will usually be behind the barrel on the LH crankcase, under the carburetter, unless it is very early indeed.

cheers for now,

Simon.

UDD registrations were issued by Gloucestershire county council between November 1957 and January 1958.

given those dates and assuming the reg number does belong to the bike the chances are the bike is either a D1 plunger or a D5 swinging arm both would have the frame number stamped on the head stock , left hand side by this date.

Thanks, for all the help.

I see some raised numbers as suggested by Charlie on the frame, just in front of the front engine mount but can't make out the letters. The frame looks to have been painted over so i will take the head stock back to metal tonight to check if any numbers are there. I'm still trying to upload photos for you all :-)

From those pictures your bike looks to be a D3 swinging arm model manufactured 1956 or more probably 1957 and if those are the original headlamp/toolbox etc. then the colour is Devon Red.

The number in the picture is a casting number. The frame number should be stamped into the frame tube where the fork stem fits through and will be in the format CD3 *****.

I don't think the toolbox is 'pointy' enough for a D5, plus the frame looks to have been black originally and the rear section doesn't look long enough to be D5. It also looks as though the rear frame bracing under the seat is a pressed item whereas I think the D5 has a tube?

Thought you had a full house Jess? It looked pretty full in that photo you posted of all your bikes wrapped up in blankets, in the shed. Or were you thinking of letting your D5 go, so you can get a D3? I got lots of space in my shed... and a lonely D5 who needs company... Hint hint!

HI chicken. Excellent information guys. Now have engine and number stamped is B D3 B so if it's for the bike looks like your D5's are safe jess and Dood Doodkie :-) and I got myself a D3 like you all suspected. 

However the frame numbers are still hard to find. I've checked the head stock and both sides of the frame near the bottom front engine mount. And can't see anything. Either it's not there or I'm looking into the wrong place (or not hard enough).  Any more info on size, length, position of D3 frame numbers would be great . We spent most of the night with paint stripper and a scraper with nothing to show. Looking on Google i can't find any images of frame numbers. Has anyone posted pics on this site? If not please can you show me below to give me a fighting chance tomorrow. To cold in the garage to be stripping paint off all the frame!!   :-)
