[R-390] Help - Need Parts for Johnson Pacemaker

[David C. Hallam]

I am in desperate need of some iron slugs for tuning coils in a Johnson
Pacemaker.  These iron slugs are for a 3/8" OD ceramic coil and are 1/4"
diameter and 1/2" long.  They have a 4-40 thread brass adjusting screw.  I
need a replacement for one that is missing and really could use 4 more to
replace ones that have bent adjusting screws.  Does anyone have some coils
like this in their junk box or parts bins?
