Zipp wheels 340 + 440 in Brentry, Gloucestershire for sale

Zipp wheels 340 + 440

Gutted I'm having to sell these. Brought them on Greatbritainlisted a few weeks back with the intention of getting them on my willier, but hit a stumbling block as after seeing my bike mechanic he said I would need to rebuild the wheel with a new hub to get my campy cassette on, or pay for an expensive conversion with may not work very well. :(
Any way about the wheels,
These a genuine zipps, they are models 340 and 440 which are old but don't have a great amount of use according to the previous owner which you can tell to be fair and there in very good condition.
The free hub will take shimano 8 to 10 speed, but free hub can be upgraded to an 11 speed one.
Bearings are very good. Spin for a long time.
The wheels have had new stickers put on as the old ones were faded, which has brought them back to life. The front wheel has got a couple of its original stickers on which is pictured. If you look at the last photo you'll see what they looked like before the revamp.
It has 2 brand new, never ridden continental gatorskin tyres on. These are tubular tyres, as these are TUBULAR WHEELS. First time I had a go at putting these on and was really easy. People say you need to stretch and inflate them for days but I pulled them on straight from the box. The tyres were fixed using double sided tape.
Still run true. With a tiny bit of play. Can send video on whatsapp or something if you want to have a look.
Branded new genuine zipp skewers.
Brand new presta valve extenders.
