Here is my completed set of Ludwig Educator's. Ludwig's failing attempt to compete with the Japanese market in the late 70,s. The drums have plastic lugs but the rest of the hardware is very solid and sturdy. Shells in this kit are 4 ply with maple interior's without rings, except for the 13", it is 3 ply with rings.
This line of drums was so short lived it was never cataloged. I myself am aware of just a few of these kits owned by fellow VDF members.
