I`d be very pleased if you could give coube of answers. I found an old Hayman snare drum and and numbers in it`s logo are pat.37613/68, pat.12763/69 and reg.des. 940779. Wooden drum is silver colored and it looks same than one at your web page. It`s in good shape however snares have been changed to tama. How old is this drum? How many was made? Where I can get originally sounding snares?...

Thank yo?,
