Can you help to identify these frames, bikes or parts?

Wondered if anyone could help me identify my old track frame, I bought it about 5 years ago it didn't come with original paint and i just got it powder coated at the time.
Stupidly i didn't check for any only decals under the crap paint before it was stripped.

When i bought it i was told it was a 50's British track frame, with Nevorex Lugs, it has a English BB and the seat post is 22.2 i think.

The only identiflying marks is it has 5765 stamped on the BB shell and fork.

Any help identifying it would be awesome..

After a bit more digging it seems likely my frame is a late F. H. Carpenter 'Olympic Pursuit', just waiting on confirming the year to see if it was made in London by the man himself or by Swindon Cycles.
But it has the double plate fork crown, came to me originally with a Stronglite Competition headset and shares identical features to the model described here.
