Wow that is very close, but I`m not see`n a knob on the throw arm like the leedy, look at the photo of the strainer in the pile of cleanning with the lugs, that looks like a rivit instead of a knob. But that could be a repair, or the knob broken off I don`t know. You might have it though cuz it`s really close and I don`t see any other differences !!How many hole are on the bottom of the leedy ?
The leedy has 12. If you look close you can see them in the individual strainer picture in the cooper's vintage drum link. I noticed the rivet also but assumed it was probably a repair. I only count 8 strand in the pictures, so either some strands are missing or the strainer is a copy of the leedy or perhaps leedy copied their design.
