I have a hard copy remaining. If nobody comes through on an Email for you, will happily stuff the thing in an envelope and mail it off to you.
The author figured about 50 of those guns were found in a warehouse, and he looked long and hard for one after turning down the chance to buy one at the beginning. The pictures in the article were unclear at best, and from what I did see, the gun had a POS (pride of Spain, or, worse) look to it.
Best,
Ted
