Are you referring to a BSA catalogue to get all that information? Which one, out of interest?

1936 catalogue: https://oldbike.wordpress.com/1936-bsa-catalogue/ I was going to say this looks like the latest catalogue where the bikes still had head clip headsets, but actually if you look carefully some do have them in the 1938 catalogue. 1936 Gold Medal has a 531 frame with the high...

You probably saw me mention in the other thread that by the 1938 catalogue BSAs didn’t have a head clip headset. So we can say yours pre-dates that (edit: I was wrong about this. The Opperman forks had head clips in the 1938 catalogue if you look closely) 1936 or 1938 Opperman Special with...

A couple of years ago I had what I’d narrowed down to a 1938 BSA Sports. Almost everything matched the brochure except a couple of small details. For a long time I wasn’t convinced it was a BSA but a lot of things were the same and it had remnants of BSA box lining. They can be extremely...

It’s not usually the small end it struggles with, it’s usually the big end because it struggles to clear the big cog. It’ll be fine with any cassette down to an 11T at the small end. So either 12-30 or 14-30 will be fine 👍

Link to the 1938 BSA catalogue if you haven’t seen it: https://oldbike.wordpress.com/1938-bsa-catalogue/ You’re right that yours is earlier than this. The head clip headset is the giveaway, as by 1938 they had threaded headsets. However, that catalogue has all the models. Good spot with the...

Could be someone over-tightened the stem bolt and bulged the steerer tube. Glad you got it out 👍

Is it that other stop notch what some of the Huret Jubilee mechs were supposed to use too? Mine has it in the usual position but some of them had it further round.

Ah ok, makes more sense now with the pics and additional input from everyone. It looks like you’d be fine filing the side of that portacatena mount flush to clear the bolt head. Another option would be, if you want to keep the frame original/untouched you could get a washer and file a notch into...

Doesn’t sound right, but without a pic it’s hard to say.

I’ve got some kit that smells like that too.

Those cable entry tubes are about 0.75” long and have a step at the end of them so the cable can’t be pushed in any further. Kalloy UNO seatpost comes in 25mm if you want a more budget option than Campag 👍

You don’t use a liner on that internal tube. The ends are stepped and (from memory) you should be able to use a well-cut cable without ferrules. It looks like the plastic on your cable outer has got rucked up, that’s probably why it’s tight. I can’t remember if it’s better to strip back a bit of...

This is lovely and what a great setting to take a picture of a nice old bike 👍
