My switch turned up today, to all intents and purposes it looks brand new, it came with new cables, new pack of ears, new instructions, and proper foam packaging, just wasn't in a Netgear box.
Need to tidy up the cabling, I bought a splitter cable for the two switches, but can't unplug the other switch to change it over at the moment or I'll get complaints.
Some quick speed tests as requested:
This one is rather slow??

Oddly running through the switch and with CAT6A patch cables its a bit slower than before, mind you one of the PC's updated to Window 10 20H2 the other day.

Much closer to 10Gbps in parallel though, although the second time I ran it was 7.5Gbps

The PC with 20H2 version of Windows actually reports the network speed correctly.
Just waiting on the card for the server now, Royal Mail 2nd class seems to take for ever now :-(
