I had a 4 player Hot Shots with the mondial inscribed on it . Seems they were/are an official supplier for Gottlieb . being a Canadian machine might mean something.. or maybe not

Also , im not sure, but I had a woodrail jockey club with the bonus missing but what appeared to be manufactured tape on the backglass, as well as a CC with a manufactured tape over bonus spot in a Drop Ball. this was to circumvent any gambling issue for use where .. a machine was deemed to have that. Perhaps blocking out credits might have allowed that machine to go somewhere.

it is definitely a sure shot, the bank shot which I also owned once has a different backglass, the lamp accommodated specials and a blank square to write down high scores.

http://www.mondialgroup.com/gottlieb.htm is their website

just to add a point of interest and possibly more confusion, I do see that apron used by this company reconfigured gottliebs, with no gottlieb name on their backglasses
