Hey Guys, Wanted some feedback on my Ham M22. 99% of the 22's I see are Navy marked. This one is US Army marked. Movement is standard Navy markings and is S/N 2F19986. The tub and rear lid are matching numbers 5627. I would think this is much scarcer than the USN ones? Army Air Corp? Any idea how many went to the AAC? Warm regards to all and appreciate any info from the Hamilton crowd.
