No idea but I like it. I like bead blasting frames and parts to start a restoration. Makes for a great paint job. Make sure you wipe it off good with lacquer thinner before you prime it. Gary
I'm going with Manton & Smith based on a lot of web surfing and direct comparison to my M&S of bike the welds,seat stays and chain stays all match in bends now to figure what model it could have been and year.
Good call--M&S. Looks to be an early frame since most M&S bikes had the slightest downtube curve. Maybe 1937ish, but there's very little reference information on the maker.
Just made another discovery! My first "old" bike a Western Tire and Auto Stores Silver Shield is the same frame as this one and it looks like they were Manton&Smith made...went from one M & S to three in the space of a week! My 1941 I believe.
