I don't want to disappoint you, but you have a fairly common version. The H-D Military was a model name and was NOT used by the military...only the H-D (with no additional designation) was used by the military. Yours was produced from 1946 to 1955 and they made 150,000 of them. Read here: " The final models, marked “High Standard H-D Military” are the most common, with 150,000 produced from 1946-55. The value of these pistols today starts at $250 for shooting grade models in good condition to $700 for minty grades with a little extra green for the older models."
