Freed transformers and chokes

[K9PNP]

Does anybody know where I can find data on Freed transformers and chokes.   Looks like they made a lot for the military and for Collins.  The normal searches don't show much useful.

I've never seen a catalog but I've seen the iron everywhere in military industrial stuff. I always thought they were mainly a contract manufacturer.

Here is some data

The Radio's 1950-51 Master Catalog has 7 pages of data and the 1958 Radio -Electronic Master Catalog has about 50 pages. Petty much full line with Mil and "Professional" grade potted types. 
That's about the only place I have seen the info.
  Most of the Freed transformers I have had where OEM or Mil numbered. Not listed like that in the books. If you could find the Mil NSN number the data under that filing might list the commercial equivalent. The TFXXXX number on some indicate the classification type but rarely yield the exact spec.
 
I can see if any numbers you might have show up in the books.

Thanks all for the info.

I agree that most have a NSN or somebody else's part number.  Luckily I still have a lot of '-P' Tech Manuals and a few NSN cross-reference books.

One I saw and was thinking about buying was a 2KV CT at 500 ma with the only number available of 21649.  Unfortunately, I don't know if that was somebody's part number or just a stock number.  Wish it would have had a NSN.
