Hello Charles,
Could you post a few pics of the kit you are writing about?
pretty much all the Japanese stencil dum kits
were intended as cheap (affordable) knockoffs of the better quality American drums
Mostly Slingerland copies but some looked like Gretsch also
While others even copied the German made Sonor teardrops
Most of the U.S.Mercury Kits had the Slingerland look
At the time Slingerland had the lower priced stage band kits
One large center mounted lug casing with extra long tension rods
as well as the better quality kits with separate lug casings for batter and resonant sides
The Japanese drums were made in both styles as well
In my collection I have U.S. Mercury drums in both styles
Both are cool and I like them equally as much
but as a working drum kit
the style with the separate lugs for each side(pictured in white marine pearl)
are a little sturdier and would most likely hold up better
Also personally I think 250.00 would be way high for the stage band style kit
(pictured in red marine pearl)
and getting very close to top dollar for the heavier duty style especially with no snare drum
That aside if the wrap is unique and in good shape they may be worth paying up for
