Looked into it, you're right...it's some model Coin Controls from the late 80s, but the catch is that my sticks were probably modified with Happ parts and I'm guessing at some point before the merger.
I say this because I've found others discussing them, these joysticks were late 80s and originally came with the micro leafs which explains the 2 slots near the microswitch (because the leaf mounted there). I'm guessing when the leafs went bad, route operators converted the micro leaf with the microswitch, and upgraded the old round actuator with a square one...probably pulled loose Happ parts out of a box like the square actuator, shaft spacer, and Happ bat stick. The original Coin Controls was a bat stick, but had more of a ball shaped top. Due to the age of the joystick, I'm guessing the upgraded parts are original Happ parts before the merger since mine looks like it has a white nylon actuator and shaft spacer (nylon is pre merger right?). One guy even commented and said the joystick I have could have been an ancestor to the Happ Ultimate, which explains why they are terrible sticks and tried to be upgraded with Happ parts.
I suppose my joystick upgrades could've been done with modern IL parts but I doubt they wouldve wasted good parts on these joysticks, which leads me to believe the are original Happ parts before IL became what they are today. One thing is for sure is that they weren't upgraded with modern Happ (pvc) parts.
