Look like Bocama Competition 78 lugs, bottom bracket looks like a drilled out Roto. All smacks of Dutch to me with a whiff of Gazelle although I'd need more photos of the other bits of the frame. The downtube bosses look just plain wrong, like they were added incorrectly. What are the threadings?
I'm after a Gazelle AA from the 70 to early 80s -- with over bottom bracket gear guides, butterfly bridge and cross chainstay bridge. About 52cm CTC plus or minus a cm. Doesn't have to be immaculate, in fact I would enjoy a project. I'm in the UK. Thank you.
no, sold long ago. Sorry
