Just to give a quick run down on these for those who don't know, they are the forerunner of the Beretta 92 series. Single action like 1911, Fixed sight, bottom mag release single stack mags. Slimmer, slightly smaller and lighter than the 92. The Beretta 951 also suffered from the locking block failure, just not near as much as the Helwans because of better metallurgy. For that matter that is one of the weaknesses of the 92, however its an easy to replace part in them, not so for the 951s anymore.
The Helwan was my 1st semiauto pistol, bought it new in the box in 1987 for $115 IIRC. I bought a couple since as well and have sold them as time went, one having the lock block give way and the other to make room for other pistols. None I paid or sold for near $200, seems like they are getting slightly collectible now. Getting a real surplussed Beretta for that kind of money seems like a heck of a deal to me.
