Quoted from boilerman:i agree with JR, The DA at the end makes sense the D in the front doesn't and if it was a 0 that would make it a 6 digit SN. they only made 1000 of them and according to IPSND there was one listed with a "D" as a prefix (this one) and 3 with a "A" prefix.... typo maybe?
This was curious to me so I looked at some of my submissions from the late 50s GTBs I have and they did appear to have a letter in front of the number for a while, and the number is different for each game: Lighting Ball was M; Auto Race E; and so on. So smohr's game seems to fit that pattern.
I believe it's a D also...I think those 'A's on IPSNDB are all suspect - two are from "pinball eric" who has tons of entries and I think was someone's list that was uploaded initially, along with The Internet Pinball Project's, and the other has a pic of a number written in Sharpie-of-the-day on the underside of the PF...so who knows where that came from. Since smohr's is obviously a D, I'd conclude those others are all wrong...
Is there a scribbled one on the underside of your PF smohr?
