Genuine 20 MM Cannon Cartridge WAR II

This ash tray was mad in 1954 from what I have learned and this Stoner MFG CORP made coin operated machine and pinball machine's
I found the estimated value price is $100 to $160 but we all know that is just some co trying to drive a price of something up.:wack:
I will let this ride here today and get it on ebay later tonight
Thank you for this great place I call home For-A'-Bodies-Only :cheers:
