[Milsurplus] Aircraft radio gear

[Curt Arseneau]

Have been shopping around for some equipment for a static display in a museum aircraft for some time. Many of you have been generous with your time, information and even donated parts. Can't thank you enough. Going to the well one more time. I have located a J-68/ARC-3 power supply including 1 each DY-21 and DY-22 dynamotor from a source in France. While the price seems reasonable (about $320) and the dynamotors are in working order (I'm told) shipping is a large expense and working dyno's are overkill for our project. 
1st question: Would anyone have the complete setup available for sale or trade here in North America? Does not need to work.
2nd: Would anyone have either the J-68 w/o dyno's or either (or both) nonworking dyno's available? 

Finding any or all of  the parts on this side of the Atlantic especially in nonworking condition, would save significant stacks of US$ to use in other areas of the project. 
Referrals to sources also appreciated.
Thank you all for your generous support.
