Roundup layout looks like the Bally Jumbo one ball. Scores the same except for the one 10 point hole having a mystery payout. Very cool & love the artwork on it. Can see that someone removed pins to make it easier to avoid the upper "out" hole. Probably not the operator, who would be more likely to add pins where a player wouldn't want them.

6 volts if it is like Jumbo, which used four large cylindrical single cell batteries in series. Your light bulb #'s, if any, could provide a clue.

All the battery games I've had were 6 Volt systems, although none of those were Gottlieb games (Bally, Genco, Jennings, Peo, etc.). They were powered by four large cylindrical carbon zinc batteries, like huge "D" cells (still have old batteries in a few games here). If you spot the place for the original batteries in your cabinet then you might be able to confirm how many cells were used (4 at 1.5 Volts per cell, in series, for a 6 volt game). Some manufacturers started adding battery doors to their cabinets, otherwise it is a nuisance to get under the playfield for a battery swap.

I'm currently restoring a 1934 Gottlieb Push Over. The wiring will need to be replaced because of dry rot. It looks to be hacked up and adapted to fit two 6-volt DC batteries (maybe?). At least thats my guess to this point. ...

Neat looking game. Wires are bad enough to be original, and then they were taped up later on. Can't tell from pics but the game might work fine after replacing the wires, one wire at a time.

Have a Jennings 4-cell battery compartment and the internal measurements are: 10-1/4" wide, 2-1/2" deep, 6-1/4" tall and currently open (no lid or retaining bar on top).

Have a nice Jumbo, fun game with lots of small payouts to keep your interest up. These look rough. Would want better pictures and description before driving 3 hours. Rock-Ola cabinet is coming apart & side door missing. Did it get wet or vandalized? No legs in evidence. What else is missing? No playfield glass & dirt could be hiding more problems (delamination, rust). Could still be ok, or totally not worth the drive. Guestimate 800 to 1200 for when they are average looking working games, in line with prices I've seen at auctions and shows.

We had fun taking turns playing a Golden Harvest at the Fall 2022 York PA show. Really enjoyed seeing it there. Plays much slower than a one ball game. Took a few games to get a winner, but no money came out (noticed the "battery eliminator" was not plugged in). Which is ok. We were dipping into the owners can of nickels to play the game.

Would have bought the game at York for the right price, or this Colorado game if it was closer.

Would a penny work? The dime seems small for that space.

Fantastic "what is it" piece and likely one of a kind. Does the seller have any info to add?

Has that Bally Bumper head plus a weird playfield from I don't know what. That shiny metal surface is similar to the Bally Mercury and a few others, but it has many more bumpers and posts. The ball shooter guide and plunger/lifter look period correct. Would expect the front of the cabinet was originally painted and don't expect to see it reinforced with metal. Those legs are too new and belong on a bingo pinball.
