Dave, The frame has a some of features similar to a couple of 1950's Holdsworths that I've seen and one that I own:
1/ The fish tails on the BB shell are similar to those on my '56 Holdsworth Whirlwind. I can check tonight, but I think that mine has the same RGF stamping, but definitely no grease port.
2/ A friend has a Holdsworth track frame with the same dropouts, but without the mudguard eyes. His frame has the same lugs as my Whirlwind, so I presume that it is mid-50s also.
My Whirlwind, and my friend's track frame have the frame numbers stamped on the LH dropout, and on the steerer tube. Does your frame have a fork?
