I looked through the pinball database but can't find the game I am looking for. It's an EM from around 1970 - 75. On my way home from school (in Germany, about 1973-76) I came by a bar that had this machine right at the window. I usually stopped to watch people play, sometimes for hours which greatly upset my mom.
I don't remember the name of the pinball or the manufacturer, maybe somebody here does. It had 2 flippers at 3 inches, return lanes (so it wasn't one of the early EMs) and the bonus counter in the middle of the play field had a bunch of navy vessels with lights indicating the bonus next to it, similar to Gottlieb's 1974 "Far out" but with navy ships. Like a patrol boat for the lowest bonus working its way up to a battleship and finally an aircraft carrier. It was a 4 player game. I am pretty sure it also had a return gate for the ball to get launched, also similar to "Far Out". It had a non-symmetric layout with a bunch of consecutive lanes (3 or 4 maybe) running down on the right side that ended with a drain or the return gate in case it was open.
