OK, I purchased a 1940's shuffleboard scoreboard that was in bad shape. My hope was to eventually convert to battery (I started a thread on that here: https://beta.pinside.com/pinball/forum/topic/converting-to-battery#post-4521744

However, my initial step was to try to get things working as intended. Not an easy task since pretty much every wire was cut/missing to the Jones plug that connects the power source to the coils and lamps (Basically, there are three mechanical devices for the scoreboard. All std score type steppers with two coils...one to increment and one to reset. One increments to light a lamp for Home score, one shows visitor score and the third is for coin-up) Other than that, a couple of buzzers and lots of lamps. Alas the transformer is shot. At one point, it seemed to be producing voltage (3 lugs showing 33, 45 and 49 VAC) but not enough power to even power a 44 lamp. Later testing (change multimeter battery) and I've got nada.

So, I'm looking at getting a new (to me) transformer. This is not a manufacturere anyone has heard of, so I'm flying blind. The coils are all marked 116-K-304 11 OHMS. Can't find any reference to these either.

Anyhow, before I just take a wild guess on a transformer off of e-bay, I'm sure someone here can help make my wild guess an educated one.

Thanks

I was thinking about heading down that path. The coils are in great shape, activate just fie with a 9-volt battery. However, the sleeves are pressed into the coil, so they cannot be removed. Now, given my desire to eventually convert this to battery, how does (or doesn't) that change your thinking about what coils to use. (By the way, they are large coils and I don't want to have to re-engineer all the brackets, to get them to work properly)

I think the coils are all fine. Yes, just one fires at a time. 9V pulls the coil without the spring attached. I assume motorcycle battery would definitely have enough punch although room may be an issue.
