C. E. Niehoff is still in business making generators. Call them and see if there archives can help.
Good idea: I tried that, and all I got were blank looks. Niehoff seemed to forget that their company existed beyond alternators. The college-age sounding gal I spoke with was not too bright on anything beyond a charging system, she wouldn't look anything up until I mentioned lighting coils.
Once I gave the number, she also told me that I did not have a Niehoff part. I didn't care to inform her that it was in the original box.
I might try again later and get someone who is willing to hunt down information on paper, knows what a condenser and point set is, and who cares a little more about their customers.
I believe Niehoff was owned by NAPA. At least I was told this years ago.
My local Napa's "old guy" remembered Niehoff, but he couldn't find any crosses. He ran a few numbers off the top of his head, rather impressive, but none of them matched what I have. He didn't remember Napa carrying Niehoff, though, but he said he could be wrong. He also couldn't remember who did carry it, so it could be a "touch of the alzy's"
Sorry no help, >>>>>>>> Just list them on ebay as vintage, and ask a high price. 
That's always the backup! 
Thanks to everyone for their answers. I've got to stop finding old aftermarket car parts in my boxes, or I'll drive myself batty.
