GE 4EX series test sets

Hello all, I am a Ham here in NC and I am trying to put together a complete collection of the old GE 4EX series test sets. I use some older GE mastr equipment so these old test sets come in handy. I am looking for the following sets.

4EX5A10 IMTS test set
4EX9A10 IF generator
4EX10A10 Calibrator
4EX11A10 Test fixture
4EX17A10 Test fixture
4EX18A10 Test regulator
4EX20A10 Test calibrator
4EX20A11 Test calibrator
4EX21K10 Ge-STAR test adaptor

Any and all help in locating any/ all of these sets would be greatly appreciated.

Thanks and 73’s

Hello all, I was hoping someone would be able to help me on this but Maybe not. Just in case someone does read the original post I know have the 4EX1C2 attenuator set and the 4EX5A10 IMTS test set which I am told is also the TL53 set. Thanks.

I have a 4EX1C2 that you mentioned in your post 6 years ago. Do you want it?
