The Whitworth's were good as firm Zastava, Serbian (you incorrectly term "Yugo") actions & complete rifles! The firm dates back to the mid nineteenth century. Been around a while. I have several and appreciate them all. One, as your latest, an Express version in 458 WM! Really nice, classic configuration right down to the multi-leaf "express sights".
As to the BSA rifles, they made one in 458 Win chambering too. And... the first edition of that really nice unique rifle from mid-fifties era, was first in CRF. Bout half a decade, not many sold. Then BSA push feed replacing. I have four of CRFs, no magnum version which I believe was limited to the ref 458.
I just can't get warm to the Santa Barbara Spain genre. Sorry! Hope it works out for you and likely no reason it shouldn't!
Best!

When I went to the Zastava factory in 1990, it was definitely in Yugoslavia
