Anyone recognise these forks?

Hi, found these in amongst a bucket load of forks from an old bike shop clearance - just wondering if anyone knows what they are from. Look like they're missing blanking plates from the top of the blades - probably had a makers name on them?
Numbered 81.11.271, weight is 640grams. 1" x 24tpi steerer tube.

I have seen forks like this on a British 70's time trial frame and fork/bike. It was a well known frame builder, but cant remember the name. Pretty sure it was british though.

What other forks are there in the bucket?

Mainly older ones - from 40s 50s 60s possibly.
I'll post a couple more tonight.
The only ones I've positively identified so far were Paris Rensch from 1948.

Another fork requiring identification if anyone can help, stamped 47 7 98, weight 805 grams.

And another, these are stamped F C and an Accles and Pollock oval logo with CM (chrome moly) in it. Look like they could b 1930s. Weight 745 grams.
