Hi. I'm looking for Nagra iii parts - notably the strap nuts and spool holders. Wondering if you guys might have an idea of where (or how) I might obtain domestically? I'd rather not buy from eBay because the only guy selling what I need is international, a bit overpriced, and doesn't respond to my messages. I don't need authentic Nagra parts - just something that works. Any suggestions are appreciated. Thx.
