70's Thomas Organ wah... Anyone know how to correctly date???

[brokenstarguitar]

I have a 70's Thomas Organ wah that im going to clean up and sell but I dont know much about it, just that its from the 70's. I dont have the original bottom plate so I dont know a serial number.

On the pot....
24-5318-3
1347751

Tag on wires...
84-22882-0

Board....
84 22865

TDK 5103 inductor
5117 transistors

The pot was made the 51st week of 1977.  If it's original, the wah was made sometime after that, probably '78.  I don't know the timeframe for the TDK inductors, but that info may be on the web somewhere.

I've a feeling the transistor was wk48 1977

I bet you're right.  5117 is the Thomas Organ part number for the transistors, I wonder if the "-2" is a gain bucket indication?
