Pre 1950s rides of LFGSS: old bikes, vintage rats, classic lightweights

Well. Looks like a. the fork crown was chromed, b. biek was lilac, possibly, or red, with red oxide primer originally and c. the only thing I can find with any numbers at the moment (have scraped everything usually where there’s a stamp, except have taken off the forks yet) is on the front bb is ‘ST 24’.
Any help helping me date this. Still looking for drivetrain.

Found this, pretty strong contender for what I have here. Might try and get the fork out today and see if there’s any stamps.

Looks very similar indeed. Check out this site http://www.nkilgariff.com/ClaudButler.htm
And explore the catalogues as it will give details of what parts it would have been fitted with.

39'-40' catalogue has good parts list for this model

Ah, top tips. Will have to write a shopping list! Let me know if you spot any parts :)

Yes let us know what you need and I will keep a look out on the Bay

So, fork stamps.
On one side - 641475 - so April ‘36, no 1475?
On the other, looks like - C 771.
Am I close?

@falconvitesse great spots, thank you. Have placed a bid on the crank set, that’s a huge win if I get those.

Cyclo derailleur and shifter -

Are you able to get to grimsby to collect though?

I think I might need to pass on a trip to Grimsby. Plus I’d end up with two tandems lol

Ah, that doesn’t look complete?

Ah, that doesn’t look complete?

Yeah, Think you're right-Looks like it needs a bracket to fit to the frame.

It’s all very new to me, this :)

Got your pm, will get back in a minute :)

Just brought that from the link, looks exactly right, thanks very much :)

Just a thought on tandem gearing

Tandems are fast on flat roads and downhill, but uphill they are a struggle (honking requires skill!). So for most non - racing purposes a low bottom gear is necessary.

I have a bike with a Cyclo 3 speed and I have tried and failed (so far) to find a sensible block. The largest sprocket I've got so far is a 21, but that comes with 3 tooth differences (16 - 19 -21). More common is 16-18-20, but what I'd prefer would be 16-18 and at least 22, and that's on a solo. I've overcome this by using a small inner ring, but this is not possible on a tandem without a crossover drive, which would, I think, be too modern for what you are aiming at.

A possible answer might be to combine your Cyclo with a Sturmey hub, which would give a further 25% reduction. I believe 22 tooth sprockets do exist for the standard 3 spline fitting.
Using a 3 speed mech. with only two sprockets may prove tricky, but would be possible.
