WICO EDISON magneto parts needed to complete one of each

[Mutt]

Can ANYONE help me in finding these parts. I need one CORRECT cap for each of the 2 magnetos to finish them. I need one for the Wico XV1922 (1948 to 1952 WR) and one for the Edison RM
(1940 WLDR / 1941-1947 WR)

I am trying to keep from using a "modified" 4 cylinder cap on either as I am RESTORING these mags.I have other XV parts to trade or a pile of other 37 to 62 HD parts I can trade. Hope someone out there can help.Thanks.......Mutt
