So Anopsis, if the vintage watches you referred to above were only available in 36mm cases, would you still want them?
Touche` my friend.
I have not shouldered a Browning, so I can't comment on it's size. The Marlin 39A I have is dimensionally very similar to my Marlin 336C chambered in .30-30, and I can shoot it quite comfortably.
I have semiauto .22s as well (not a 10/22 though) and I have friends who have both. They each have their place, and the 10/22 can certainly be modded to whatever state you'd like - there is no end to the combinations and aftermarket parts.
However, since the OP specified a couple of leverguns, I ASSuMEd he wants that style specifically.
Besides, for all we know, he's a shrimp and your baby Browning will fit him fine.
