Can anyone identify this, probably very old, TRV? I've seen one like it called the Draton TRV4 but it's not exactly the same and I'm keen to be able to replace the existing one without any messing about with the pipe or rad. The problem is the little brass pin is stuck almost fully down and although there is some movement, no amount of tapping will release it. There's a fair bit of scale around the pin too, so it's best to replace I guess.
I could ask the Draton people directly of course. I suspect its an early version of the TRV4 and hopefully the dimensions of the fitting is the same for the newer model.
Thanks for any help.
