Vintage BSA frame & fork with original brass headbadge (Birmingham Small Arms crossed rifles design). 1 inch headset. Takes std english bottom bracket. 120mm rear spacing. More photos & details here;
Cleaned back to fresh metal and re-sprayed a lovely black. About to be completed with fresh decals - white "winged" BSA decals for each side of the down tube and a gold "BSA Crossed Arms" logo for the front of the seat tube.
Would make a fabulous fixed gear (unique & characterful unlike a Langster et al...) or an elegant vintage style road bike. Maybe even get your LBS to re-space the rear to 130 and put new gruppo on it as a contrast?
Lovely and unique however you build it up.
