hink441 Posted November 20, 2020 Share #1 Posted November 20, 2020 I have had this shell for awhile now and am trying to figure out the age. This is a steel shell and has “2-57” on the bottom. My question is; is this the date of the shell? I always thought the steel shells came a little bit later than 2-57. Link to comment Share on other sites More sharing options...
917601 Posted November 21, 2020 Share #2 Posted November 21, 2020 Steel was being starting to be used in late WW2, (Norris patented it)covered in brown lacquer. Phosphate finish like yours was late fifties and later. Now this, the CRA inking “82B....” means Crane, Feb 1982 loading. The “ MK number” also seems like a later series number ( I would have to check Navy Data sheets). Not uncommon to see manufactured surplus cases stored and loaded 20 years later. Also true with Army cases, I talked to a 105 howitzer red leg and he said his guard unit in the early 90’s had 105 cases headstamped from 1945.

917601 Posted November 21, 2020 Share #3 Posted November 21, 2020 Confirmed- from the Nav weapons site, the MK 9 case was steel manufactured to 1990. Link to comment Share on other sites More sharing options...
917601 Posted November 21, 2020 Share #4 Posted November 21, 2020 I did not clearly tie it all together. Your steel case was manufactured in 1957, loaded ( assembled into a live round) in 1982. Unable to determine by the inked numbers what type of projectile was loaded into the case ( HE, AA, AP, Illum., etc). Link to comment Share on other sites More sharing options...

Thank you for taking the time to get that info!!! Chris Link to comment Share on other sites More sharing options...
