Subscribing! Never seen such headlugs before (they look hand-cut) nor anything with all those details but suspect the braze-on shifter boss is for a Simplex unit. Will be interested to hear what some experts say...
Is it confirmed to be Imperial tubing and BSC threaded? Have you got a seat post size?
