I've got plenty of these so if you can just give me a day or so, I'll dig them out today, play test them, and post some pics
EDIT: Update: Both guns are play tested and work great. Here's a quick pic.
Had to leave to go to work though, so I'll PM you with details and such later tonight.
I think this will help. ALL Brand New Guns. I have a Johnny Nero Action Hero and also a Time Crisis 3 (probably all of the TC series also). I spent countless hours researching this and I also live 15 minutes from Happ (now called SuzoHapp), so I could bring my gun there and compare it. I did this 2 weeks ago. The JNAH original part number for the 2 guns, Red and Blue were AH2010 and AH2011.
Here is what I purchased from them and also below. These do not have a recoil solenoid in them. They come with a 4 wire plug and the same color wires that the old guns used. I was able to Directly plug it into the JNAH motherboard. I also noticed that they carry a few other light guns that were used by other Arcade manufactures.
So, In my case, I also needed the recoil solenoid inside the gun. No longer available as a combo gun, but... Surprisingly, the molding is still there in the Happ guns to support the recoil. You will have to either move your old solenoid, or purchase brand new ones (see below). You will need to add 2 new wires and a plug per gun into your Arcade to get it to work. PLEASE PAY ATTENTION. Wiring a solenoid backwords WILL cause it to move backwords and possibly blow out your gun! FYI, the JNAH game when I bought it, came with a blown out bottom. Don't know if it was due to a malfunctioning solenoid or a bad wiring issue. Probably better to get a new solenoid.
