Thanks for the clarification.

Scotstoun built mountings up to the twin 5.25", I can't find any reference for anything larger, and it is my impression that they did not build any of the guns for their products.  They did do the upgrades for the 15" installed in VANGUARD, so the erection pits do still exist.  COW did build 15" guns, though I suspect those facilities are gone, and did build the turrets and mountings for 15", and some of that capacity apparently remains.

Harlond Wolff used the facilities to build diesel engines for a period and did return the Scotstoun plant to the production naval gun mountings in 1936.  With the increase of British capacity in APOD, I think that some might be invested in expanding this facility, at least to the ability to build 6" turrets, and possibily 8", though this is a stretch.  My point was, (and made badly on my part), that if Scotstoun picks up more of the production for the smaller medium calibre gun mountings, that leaves more capacity at Vickers.
