Hi Hans,

You mentioned an alloy headlamp: I have just picked up an early-ish Bantam (1950 spring frame - 1951 engine) and in the box of bits which came with it was a bashed about alloy headlamp shell with the same interior as you have in your finished headlamp shell. Do you know if the alloy version was an after-market replacement? Thanks also for pointing out the differences in silencers for rigid and plunger: I'd ordered a new one for one of my other Bantams (1950 rigid frame, 1951 engine) and it has the plunger indentations. Fortunately the box of bits contained an original rigid silencer sans indentations, though the baffles have probably long since departed, and at least I can use the new one for the newly-acquired 1950 spring frame bike.

Does your 1948 have the three-magnet flywheel? My D1s have the six-magnet flywheels, but one has the Geni-Mag coils. I've seen mention that the six-magnet later flywheels can cause the bulbs to blow: is that why you fitted a regulator?

As an aside, my third Bantam is a 1955 spring-frame D3 in very oily rag condition, though it's a genuine Perth-delivered matching numbers D3; Mortlock Bros., Hay Street, being the sole importers for BSA back then.

I think I might have to live with play in the forks on both the D1 bikes, as the work involved in fixing the bushes sounds pretty full-on.

Thanks for the running commentary thus far,
