1929 plymouth wheel cyl

Is the coil bad or is it the switch?  The coil is hard to find but can be replaced by prying back the prongs holding it on to the switch if you find one.  I just hid a modern 6 volt coil under the dash to run the car until I eventually found one at Hershey.

What's wrong with the one you have?
My ignition switch/coil on my 30-U had a bad barrel in the switch and I took it apart and removed the barrel. My local locksmith came up with a new barrel/key but it did not fit very well. But I still could turn the switch on and off. The wire that feeds power to the coil now has a switch in it. I mounted a lock still on/off switch on the dash which now requires the switch in the ignition switch/coil to stay on all the time. The 3 contacts in the coil now are always closed. The new switch in the wire that feeds power to the coil is now the ignition switch.

I'm looking for a ignition/engine coil for a 1930 Plymouth model U. Got any idea where I might find such an animal?

I don't think so. The '28 through '32 used part 79190 on all four wheels (the '33 & '34 also used them on the front). This is/was a 1 1/4" bore cylinder.

Not sure what the Power Wagons used, but the late 1940s Plymouths were using different part numbers with, I think, a 1 1/8" bore.

See https://www.ply33.com/Parts/group5#5-S for what I think I know about this.
