Thread: Hi-Standard Model H-D Military

Hi all, I recently acquired a Hi-Standard Model H-D Military .22. I'm trying to find out some information on this sidearm, like what year it was manufactured. I have found out the basic history of the model, but can't locate where to match up the serial number to it's manufacture date, anyone have any info on this?
