60mm M720 HE mortar

[917601]

I picked this up recently, a few questions. First the markings. Body: "60MM M720 RVP79D002-002" Fin:" VGA80A001-005. H" Fuze: "M734 M.O. FUZE". The body is filled with a hard red clay like substance. Am I correct thinking the body is 1980, and the fin 1979 manufacture? It seems any post Vietnam era mortar and parts are very hard to find- plenty of WW2, Korean and Vietnam era seem to be found but the more modern stuff seems scarce. See pics.

The body was made by Norris industries of Riverbank Ca, in April 1979 and the fins were made by Van Guard industries of East Gadston, Al in January of 1980
