Purdie: I haven't put the magnet, I will try to. Thank you all, hmm, it seems that it is very mysterious snare, I am gonna explore the history of it deeper. I bought it 15 years ago with a whole Mapex M Fusion drumset, previous owner was using this snare as additional piccolo.
The reason I asked you to put a magnet to it is because I suspect that drum may be chrome over brass. There is no discernible pitting. Is it a heavy drum?
That 'could be' a quality drum. At least somebody seems to have gone out of their way to create a drum with a 'Ludwig-like' super-sensitive style strainer system. The hoops are probably Asian manufacture I've seen those hoops on MIJ kits. The offset lugs is something you find on Ludwig piccolos, again a copied design. This little drum had to be the top of somebody's line of products. I'm really starting to think it's Russian.
Do the magnet test. If it doesn't stick and it's a heavy drum, chances are it's COB. (Chrome Over Brass) The only way to know for sure is to take a pen knife and gently scrape a little metal from one of the lug holes. If the metal underneath is yellowish, not silver metallic - it's brass.
