The Rotol 4 blade prop for a Buchon is a R116/4F5/4. The R12/4F5/4 (or the R5/4F5/4 depending on the reduction gear) is the Rotol 4 blade prop for the Spitfire. The hubs are essentially the same & are interchangeable.

I was reading about the restoration of the Seafire, and it was said that one of the most difficult things to replace, was the propeller.

Alan, what restoration was this? I’m surprised it says the propeller was difficult to replace. There are plenty of options for hubs, new blades can be made & most parts can be manufactured if needed.

Some fo my shots from today. The MK1s are becoming something of a favorite of mine at the moment.

Cheers, Jamie.

Just for Sopwith, an update piccy.

Nice to see the prop back on, its looking good. Just out of interest are they original Rotol blades or new build? I assume that original Seafire blades are quite rare?

Cheers.
