What cabinet was this originally?

Cabinet date was like in January or June of 1983, I think, knew it was converted and I actually ended up finding the conversion kit manual on the inside of the machine with an inch of dust on it. The current game came out in 1985. Let me know if you can identify what it was before. Thanks! I'm guessing the conversion was done fairly early on in the 80's, the only screen burn I can see is from this game and as I said, the manual was caked. Coin door is also newer I believe, so maybe it's not best to judge off of that. Thanks! I don't think I'll be converting it back because I really enjoy the game but it'd be neat to know what it was in the past without having to rip it all apart.

Awesome! Yeah, I'm sure that is it. I guess the conversion kit didn't come with new front glass, it's still the same. Thanks so much! Interesting. The coin door actually is the same, must just be in really good condition, then. Awesome. Also seems to have the same power supply in it, still.
