Comment by W.B.lbl:
{Images #3448932 & 3448933} looks like a post-1931 pressing with older label stock. The deep groove dimensions here appear to be 2.6875" on the inner end and 2.8125" on the outer end, would I be correct? (If the pressing were 1927, the deep groove would've been smaller - 1.125" inner, 1.25" outer.)
