I to wish someone could run down and post a list of Claud Butler builder marks--that would score a big one for this hobby.

>- Nervex Lugs.
>- "A" on the left rear of the seat cluster - but probably a Nervex
>- Long-ish rear triangle - about an 1.5 inches between the tyre and the seat

>- No-name forged drop-outs front and rear and no mudguard eyes on any.

>- Number on fork column is '08609' or '60980' depending on which way up you
>- Wrapover stays which have been very nicely done in that they are fluted (as

>but the builder has continued the fluting over the wrapover by in-filling
>with blazing and then filing it to meet the profile on either side.

>No rivet holes for headbadge - so presumably not a Holdsworth then...
