Experimental Aluminum Mk II Grenade Body (Fact or Fiction)

[Stressman]

Has anyone on this forum ever seen any information on an experimental aluminum-bodied Mk II grenade feasibility study that was apparently conducted by the US Ordnance Department at the end of WWII?  I have been scanning through the 180 pages of grenade-related posts on the British Ordnance Collectors Network (BOCN) during the past several days, and I stumbled upon two mentions of this feasibility study.  They did not appear to know anything about the program, but they claim to at least have heard of it.

I posted this here in 2016.It is a well made grenade body.

Could these been for a die or casting piece for a mold?  Often you have to cast an item or make a pattern and just thinking these maybe were used in making molds? 

 

Maybe reach out to the US ARMY ORDNANCE Museum at Fort Lee. Maybe they have records or a historian who can access the information
