the way the hub is made up , riveted bearing house looks very much like a bsa hub i have here but the shoes are wider on the one here , so still not sure , my guess is bsa , having said that the ancour is very low , G13 maybe ?
bsa y13 , rocker boxes , carb manifold other odd parts , no heads , can go looking for pre unit triumph parts , very interested in SU carb , anyone interested
