1944 BSA No. 4 Mk 1 (T) Less Telescope

That's the reason why they'll rarely, if ever be modified. No swivel because who's going to use it in the single-point position? Not staked either as with no telescope...

So how to explain all of these rifles (including Surpmil's late entry in Post #20) with staking and rear swivels that aren't any advantage unless there's a center swivel?
