My previous link www.bikeforums.net/archive/index.php/t-208881.html
has the banter with Ken Bird and Clive Stuart employees, they talk about rebadged bought in frames from Holdsworthy having 3 digit frame numbers, as yours does. Although maybe this is just coincedence?
Classic Rendezvouz makes reference to Ken Bird frames being built by Holdsworth and Chas Roberts. www.classicrendezvouz.com/British_isles/Bird_Ken.html
There is a bit of chatter on Flickr, with an article from the "comic" talking about Bill Gray building the Bird badged Engers bike and Dave Clark from Mercian building on Ken Birds premises.
The only reference I can find to Alec Bird building most
of Ken Birds frames is a line in one of Hilary Stones LFGSS adverts.
Although I also saw a comment written by Simon Bird (Kens son) saying that he remembered his dad building all the frames himself in the Green St Green shop, so I guess this is an example of the truth being lost over time? www.vintagelightweights.co.uk/2011/11/1 ... /#com-head
The 3 digit frame number does make it look like a Holdsworthy built bike maybe? The Niki Graff site talks about some of there builders.
An finaly, I promise
, the 1st link also talks about plastic Unicantor saddles being popular on Clive Stuart bikes, who also rebadged Holdsworthy frames with there 3 digit frame numbers. Although I don't know if Clive Stuart bikes would've been available after 1981, when others could've got Carlton lugs?
