could well be 67672, which would make it an M4A3(76) HVSS built in March, 1945.
Could be. I was just looking at my photos and the "6" on DTA tanks had a rather deep impression on the top stroke of the loop that I would've expected to see.
We should not limit the possibilities to HVSS or 76mm tanks. It could have started out as any variety of large hatch M4A3.
