In 1961 the Holdsworthy factory did not do "Special Builds", but the WF Holdsworth shop at 132 Lower Richmond Rd did. These do not show in this catalogue.

The "Specials" builder was Reg Collard. He tells me he made quite a few time trial framesets amongst others. These had track ends with mudguard eyelets, as most folk TT'd on a fixed wheel until the mid 1960's.
