The Amphenol 83-ISP-1050 drawing is available from Digi-Key on their 
website.
https://www.digikey.com/htmldatasheets/production/2459657/0/0/1/83-1sp-1050-drawing.html

Note the dwg shows how the barrel is to be stamped and includes the 
49190. What the number represents however is not shown/stated.
