Even more intriguing to me than the mounting stability is the affect of the deflection of the action upon firing would have on a well clamped scope tube over a fair number of cycles. The No.32 bracket's rear contact surfaces have some built in fore and aft "slippage" and it's robust construction would prevent transference of most strain to the scope tube proper.

BTW, it's more than a purely theoretical concern, I've seen more than one commercial scope that's failed through it's turret! (One piece designs-not so much, but I THINK Pecar tubes are assembled to the turret like most of the time period.)
