Hi roythebus,
sorry for the tardy response to your very kind message. I'm newish to RMWeb and thought I would be alerted to any response.
Here's a photo of the dreaded HP2M....mostly hated it would appear but I have a Ks Fowler tank with one installed and it still runs OK.
I think it was my fault that the Terrier motor went AWOL!
Anyway, if you can help I would be very grateful,
thanks
John
