help finding specs on large stud mount rectifier

[GuyfromMontana]

I have read the first thread and tried the suggestions. I'm still stuck. I have about 50 new stud mount rectifiers from an aluminum plant. They are 3/4" thread studs and have ceramic insulators which implies they're fairly high voltage. On half of them the only marking is AA6RW51TRK2 then the direction symbol and 0007 . On the other half the lead is enclosed in red shrink wrap , the numbers and forward direction are the same but the last four digits are 0216.

If there are any guides to decoding stud mount rectifiers I have another 30 or 40 that I'd like to identify.

Thanks for any leads or ideas

i found some more info - I found some boxed with a GE metal label around the lead with the numbers 6rw51tr
there are two fiberglass labels also affixed - one reads TR and one reads 45
The box has the number 80-24-095 but they may be bin location inventory numbers.

I also found this tag in the bottom of another box - what does grade 40 mean ?

What you have may be like this one offered on Ebay for an obscene amount of money. Normally rectifiers like these have the cathode connected to the stud, but yours appears to have the anode connected to the stud. That may be the significance of the "R" in the part number. They generally have reverse voltage ratings of 200 V or more and forward current ratings of several hundred amperes. With the proper test setup you can verify the reverse breakdown voltage and the forward current rating.
