hi, i'm by no means a font of knowledge on these things, but the lugs are identical to those on my track frame which was built by Derrick 'Rick' Powell originally of Carlton Cycles. He later set up his own business building frames. Mine has Campag Track drop-outs and as far as I understand Rick re-built the rear end when the frame was restored so that is the primary difference. I've attached a few pics of lugs & BB so you can compare. Hope this helps you in your quest.
