After having a think I remembered that it was very possible that I had a spare VK30 engine. So I looked and to my surprise I was right.So now I'll have to fit it to the base and attempt to get it running now.I'm happy at the fact that it could well be the engine that originally was on this base.I just don't know if I will be able to find the right bracket and chrome hat it would have had. This is how it looks right now.
