Wanted, backplate for Horstman 3 channel programmer

[ProDave]

I am looking for the back plate for a Horstman H37XL 3 channel programmer, one of these

It differs to a normal central heating programmer in that the back plate is a bit wider and has 8 terminals.

Anyone have one lurking that they don't need?

It's only the back plate I need, none of those for sale on their own.  I am watching the second hand one on auction if that does not go for too much it will give me the back plate and a spare programmer.
