I'm having great difficulty in finding anywhere that sells bog standard

in order to get a knob? Can anyone advise?


By Bog-Standard I expect you don't mean a TRV.

No, it's the simple, old-fashioned, turn-it-yourself valve.

So given that, what do you mean by a "top" and how do they differ from
a knob. Is a "cap" the plastic part that makes a valve into a lock
shield valve?

Most sites call caps 'caps', but I think I've seen one or two refer to
them as 'tops' or 'covers' (like this)

which isn't what I want. I want a knob (about a dozen), like the one on
this valve:

Hen's teeth seem two-a-penny compared with knobs.
