Hi Gunnar.
This kit is a conglomerate with different drums, hardware and other parts (owner has a not bad hands..) :)
1. Snare is the last model of german TROWA - it was produced just before rename to TACTON in 1970. Good sound parallel action snare with round eccentric managing and stamped/welded stick-saver's hoops. As Dule said correctly, original mechanic is really missing...
The shell is 3-ply beech with force-rings, 6 lugs.
2. Snare stand is Soviet "EPOIMI" (made in Engels town).
3. Two of cymbal stands is EPOIMI too.
4. The middle cymbal stand is the last TROWA & following to TACTON, produced from 1970 to near 1977.
5. As Gilnar said, HH is Chech AMATI.
6. BD and FT are TACTON (II - III model) in original, produced from 1970 to near 1984. These have a birch shells (as variant these can be without force-rings).
7. Both of rack toms are EPOIMI changed to TROWA's mounts (not bad job). Shells are from birch, maybe with force-rings or without them.
The upper hoop on deeper tom installed from TROWA.
8. Toms holder is assembled from original TACTON parts with help by one bottom bolt from most oldest version of EPOIMI's stands on this holder...)
That's the end of analysis. :)
Below you can see TACTON kit of the same era in the best original condition from the far Russian town Abakan placed in the Siberian taiga forest.
As Jonni said - a destiny of this set is in your hands. You can get a good sounding kit. That's right.
Good luck,
George.
