Browning Superposed Forend ~help needed~

[jpc]

Need help with calibers

1) The larger forend measures .795" at the narrowest part of the front channel.

2) The smaller one measures .730"

I would think (1) is 12 ga and (2) could be 16 & 20

Any thoughts on my guess ☺

take care and thanks

Need pics from the bottom to see if they are a "Y" Inlet or a
"U" Inlet and side on to see if lightning which it seems they are
probally a 12 and a 20 they didnot make a 16ga and one of these are the cross bolt style
28 and 410 were not made until 63 and these look older than that

Also, 12 g superposed were available in two action strengths, corresponding to a difference in height of the receiver. This would affect the forearm inletting as well.
