yokomo ZC-641G oneway spur gear adapter prototype?

[crusaderlyf]

yokomo ever released the oneway spur gear adapter ZC-641G，can use the common spur gear on dogfighter. masami's car also used this part in works'89.the part including 4 ball bearings(two one-way bearings).I am not sure the part released day. recently I got a part，very similar as the ZC-641G, it looked like hand-made or machine-made for long time,with four holes for spur gear,with 3 ball bearings(one one-way) and the thick spacer.any one has idea about this part?or who made this part?is that yokomo prototype? thanks

I have a couple of those kicking around, they came from German YZ10 '94s.

That could make them Graupner aftermarket parts then. Cool stuff!
