Viking Southend engineering parts wanted

[notav8]

I recently acquired a Viking outboard. It isn't the most modern or streamlined outboard I have seen, but I love it. Unfortunately , it has been partly dismantled, and parts have been lost. Can anybody supply parts or info please..
Parts needed are , piston, Carby, water pipe,and a clutch. The driveshaft is also missing, but I may be able to make one.
I would consider a complete engine in any condition.
Thanks in advance.
I am having trouble uploading pics, so will try again later
