I bought these from Judah Siomos, son of John Siomos. The two items I purchased were a custom snare and an original ching-ring.
The ching-ring looks to be original and could very well be the actual one I've seen in videos of John playing with Peter Frampton back in the 1970's.
The snare drum is not what we think of today as far as a custom drum. The shell appears to be a late sixties/ seventies Gretsch 6 ply shell. The only thing I can see that is different is that the drum was drilled for a Rogers strainer & butt plate. The plaque reads "Custom Built For John Siomos by Paul Jamieson". At the bottom it gives the date 12-76 and the number 003.
I did some research on Paul Jamison and what I was able to come up with was that he is a drum cartage company and he did these snare drums on the side. At some point he started using Radio King shells and gave the drum a sunburst finish. It also appears that all the work was actually done by a very young at the time Pat Foley.
Originally I was going to display the drum as is but there is far too much corrosion on the hardware and collar hoops to let it go. So I will be cleaning it up a bit and giving it new heads and wires. Since it has a Ludwig silver dot on the batter I'm going to replace it with the same.
