Broken Drayton TRV4C head

[Schnauzer Bites]

I updated an old TRV3 many years ago by using the TRV4C conversion kit including replacing the black plastic locating ring fitted in the top of the body with the support ring in the pack.

As the head has broken can this be replaced with a TRV4 head or do I need to buy another TRV4C conversion kit again? Main reason is simply cost as TRV4 can be bought for less than £20 while the kit is over £50.

Thanks for any advice.

My TRV4c has failed. I bought a TRV4 replacement but the screw connection will not fit. I am looking for a replacement as there must be non drayton ones on the market surely?
