Help, Holdsworth?

Hi, just bought this Holdsworth and it looks correct but the numbers don't add up although I believe they did make 3 digit frames (shop built?)

Re: more pics

A few more pics for identification

Holdsworth did use 4D numbers in the early 60's and it seems again in the early 70's. There are several examples of 3D numbers use when the number were below 1000, see excel file in link below. This assumes no other numbers are marked on the bottom bracket.

I suggest that you look at the history site and try and identify the frame from key ID features. That should narrow it down to the periods above.
