It seems those pics got circulated last year and attribted to Charlton Heston.
"The gun collection actually belonged to the late Bruce Stern, rather than Charlton Heston. Mr Stern was a lifelong military and gun collector. An attorney and Vietnam veteran, he was involved in a number of military and firearms related organizations. He was a member of the National Rifle Association (NRA) Board of Directors. Mr Stern passed away in July, 2007.
The Stern gun collection became famous among firearms enthusiasts. A portion of the extensive collection was auctioned off in March 2008 by James D. Julia Auctioneers. The auction, which included firearms from other collections as well as Stern's, raised a record-breaking $12.7 million. Photographs of items from the Stern collection are available on the Julia Auctions website. Another part of the Stern collection is set to be auctioned in October, 2008."

"A Rheinmetall Germany FG42, Second Model machine gun was not only a choice example but also one of only a few currently known in this country. It carried a presale estimate of $50,000-$90,000 but saw tremendous bidding competition and ended up at $149,500. There were a great number of rarities within the Class III, many of them bringing far above their estimate. A rare and outstanding Johnson Model 1944 light machine gun, carrying a presale estimate of $10,000-$15,000 flew to $74,750. A British Sten MKI sub machine gun, estimated at $7,000-$9,000 brought $32,000. A U.S. Browning machine gun, cal .50M2HB, manufactured by Colt and estimated at $29,000-$39,000 sold for a final price of $51,750."
