There was a production run I got years ago on eBay. Full set but very inexpensive and I thought inaccurate and cheap. If I can find them or dig up photos, they are yours. They came in two labelled boxes and were made in China (same sort of look as the licensed/unlicensed Phurba). They are probably still around but I suspect not up to your standards unless a Halloween throw out kind of things. ob1a's were nothing short of stunning and I kicked myself for not getting one.
