jury is still out: it has a BSC BB, but with those other details it's clearly a late "70s early '80s frame so can still be FR from a maker who switched over to BSC threading (as several did). Here's the clincher: measure the outer diameters of all 3 main tubes, the top, down and seat tube with a good caliper. If the dimensions are even millimeters (or very close) it's metric tubing and has to be French (or other Continental origin), if they are accurate to inch dimensions (1 inch= 25.4mm, 1.125"=28.6mm) then it's Imperial tubing and not French.
