Indeed it is. It's a lovely engine too, runs sweetly. If I had a few spare £s right now, I'd be all over it like a rash. Sadly, I will have to make do with my CS & JP4...
I know the seller, and he's a solid honest bloke, so anyone buying this need not fear being done over or otherwise scammed. Sadly, I no longer have my crane truck, so I couldn't pick it up on behalf of a US buyer, I could probably find someone who would offer that service though, if needs be. It would just be an introduction though, I don't know how much a transporter would charge to collect & store until international shipping could be arranged.
