Hi all, my name is Terry and I am an alcoholic! Oops, sorry, wrong forum!

I have inherited a MTB that I believe was built around 20+ years ago. I don't know anything about the model, but have managed to find some information on the net mainly thanks to folk from Scale Models Forum. It is one of those guys that recommended I try here for more help.
The boat I have has the registration PT201 on the hull. This I assumed to be correct and so started searching for information about it. This lead me to believe it was a Higgins 78 that was transferred to the RN and served in the Med as MGB181, later to be transfered to the Yugoslav Navy. Anyway cutting a long story short it turns out that my boat looks more like an Elco 80 than any other type of boat. So I have decided to restore it to either a RON 29 or a RON 34/35 boat. My preference is towards RON 29 as they served for longer under British jurisdiction in the Med and saw more action. Fleet numbers are PT552 - PT563 for Ron 29 and PT498 - 521 for Ron 34/35.
My question is, does anyone know of anywhere I can find images and data about these boats?
I would also be interested if anyone knew of any kits or plans that this boat may have been built from!
Any help would be most appreciated.
Terry
