I discovered this problem when trying to adjust one of the thumbwheels only to discover that the other wheel turned with it. It appears that the threaded shaft and at least one of the wheels had rusted together enough that the shaft turned in the stand offs at either end when someone previously tried to adjust the derailleur. A bit of judicious peening on the standoffs with a pair of nailsets solved the problem. I applied grease to the threaded shaft to hopefully prevent the recurrence of the problem.

For the rest of you trying to follow this convoluted verbiage, the two knurled wheels in the photo above are the high and low limit adjusters. The metal tongue on the front plate hits the the inner faces of the wheels which limits the travel in either direction. Spinning the wheels moves them back and forth on a threaded shaft allowing adjustment of the limits of travel.

I have those Dunlop Super Lightweight 27 x 1 ¼ rims on my 1952 Rudge Aero Special as well. It’s still under rebuild, mainly because I have been off on other projects. But I took a few first rides, and the rims were fine! That is a very good-riding bike!

I have a 1950 Carlton Flyer. When Carlton first started offering ornate seat-tube transfers, sometime in the late 1940's I'm assuming, the model name was placed right in the middle of the transfer itself, have you looked there for the model name?




In the mid 20th century I understand that in England there was no tax on replacement parts but full taxes on new bicycles. Therefore, it was economically smart to buy a new frameset (tax free since it was considered a repair part) and move all your parts over to the new frameset. So there are a lot of english bicycles riding around with old parts and newer framesets. Your 'Carlton' logo was used from <= 1950 to about 1965 (I have photos of a Franco Suisse with it). I believe your 'Reynolds' tubing decal is much newer, maybe late 1950s or early 1960s - the decal on my flyer was absolutely tiny, about 50% the size of the later decals. The bike had crash damage and needed a top-tube replacement so these transfers were wiped out with the repairs.

Thanks for the information Don! Have you built up your Carlton? I would enjoy seeing more photos.
No model name on my seat tube sticker.




It finally sports a set of GB hoods thanks to a generous friend.
