Rear Wheel for Road bike, 700c (Hollingbury BN1)

Hi - I am renovating an old road bike for use as a cycle trainer. The only thing now missing is a rear wheel. I used to have one spare but 'foolishly' gave it away on Freegle a couple of years ago! Now wondering if anyone has one...

It needs to be 700c size, preferably with something like a 7 or maybe 8 speed cassette. Exact spec not too important, the rest of the parts are Shimano/Mavic but they don't have to match! Inner tube and tyre condition not important.

I am based in Hollingbury and could collect locally at your convenience.

Thanks very much.
