Ash Pears!
Your drums looks faboulus! -And the original Hayman vibrasonic drums are definitly collectible drums. They were "the loudest drums" you could find in the early 70:s. Great drummers like Bill Bruford (from "Yes" and "King Crimson") played Hayman drums.
However, as "gantro" points out. Your drums are from two different periods.
The yellow badges were used from 1969 to 1973.
The white/silver ones where used from 1974 to 1975.
I have a feeling that your kit was put together from orphants. Simply, someone have collected drums from different years to put a kit together.
And, the wrap is propably changed on the drums as well.
Hayman has never, as far as I know, made any drums with glossy black wrap.
The original "Hayman black" was a dull ,brushed, black wrap.
Furthermore, the tom holders on your drums are not original. The original tom holders were known as "Knuckle crushers" simply because they were so hard to adjust without getting your hands or fingers destroyed while attempting to do so. Another difference between the yellow badge era and the white/silver era was that the lugs were abit different. -The earlier ones was all made in metal. the newer ones had a small piece of black plastic attached to them. -Your pictures indicate that all of the lugs look the same on your drums.
Myself, I have a black Hayman kit with mixed badges. 13", 16" with white/silver badges. 14", 22" with yellow badges. However all of my drums has the brushed, dull black finish. And all of the drums are made with the "knuckle crusher" mounts.
