Mark!
I will look around in my non-inventoried parts bins but I can't promise anything as I have many to look thru!
You might try Larry at Cherry Restorations as he has been in the hobby for more than 40 years and has accumulated many hard to find parts!
Recently helped me with some hard to find Watling parts and he is very reasonably priced and great to do business with!
Here is his link below:
http://www.oldslots.com/Send him the photo I posted of your base plate assembly with notations just for clarification on what you need!
The sliding coin catch plate, the operating lever, the shoulder bolt the lever pivots on and there is a return spring as well!
The point of contact of the lever that goes thru the curved slot in the base plate is on the reel timing lever so it resets on every handle pull!
Bona Fortuna!
