Need new TRV head unit

[Jamiem24]

Hi all,
I have just moved into a new house and it looks like the previous owner has taken all of the TRV head units with them. I'm trying to get new ones, but the valves appear to have threads. Is anyone able to help me identify these (see attached)?
Thanks!
Jamie

Jamie he's not took them, they are old valves, heads have stopped working you will need to replace all the valves, even the radiators are looking in poor condition, is this your own or rented ? if your own you should have got the system checked B4 you bought it, if rented then it's the landlords problem.

Look like old Honeywell ones

Barlo/Quinn or Caleffi. Best to replace altogether.
