One more observation about the A-34C. It weights less than the M-32C even though it looks the same and is slightly larger. I won’t know for sure until I disassemble the M-32C, but I notice that the metal tray of the A-34C is quite light, 122 grams. This is noticeably lighter than the Pro-37v2’s metal tray (though I don’t have a weight reading for that). So I’m guessing that the tray is thinner on the A-34C than the tray on the M-32C.
