Sorry their voljon I thought you were after the Victa numbers.Their really isn't a lot of numbers that could be much use to.The number on the ignition plate to me looks more like a cast number,I think a patent number,maybe.Which is P2123. Their is a Spec No Fw (Whatever that means) 1391.Then a serial number (Which would be different per item) this one is 414159.Flywheel not much that I can read on this one.The cast number of which would be a patent number (I think) is P2124,but in saying that their is a Pat no (which also could be a patent number)(I really don't know).The Pat No is 491.110.Their is some other number but I can't read on this flywheel I didn't get time to check any others.Their is no numbers on the coil set up or points and condenser.
I'm not sure that this will be of any help.
