Thank you to all who replied! Francois85 Merci beaucoup pour cette illustration très intéressante. Si possible pourrais-je obtenir de vous une image haute résolution de cette illustration?
This must be a Ransome's Wizard as you all say and must be the 7hp model from the diameter of the piston which is about 5"; the stroke must be at least that much also. Flywheels are 30" diameter and 4" across the rim.
We have got the engine out of the bushes and into a secure location. While it had been where it was for some years, that was not where it was found or used originally.
No sub-base found unfortunately and I don't think it it ever made it to the location where the engine was latterly, as from the rust it appears to have been separated from the base long, long ago and perhaps there never was a sub-base. Other than the loss of the engine tags, lubricator and a cover plate, it appears to be very complete and potentially restorable.
Unfortunately no information on the history of this particular engine has surfaced yet. The eccentric which drives the injector and oiler fractured at some point and that appears to be what caused the engine to be abandoned.
I'm gong to make up a temporary steel dolly so it can be moved around more easily and we'll see about getting it prepared for possible restoration in future.
If anyone one has more illustrations of photos, especially of the missing parts, those would be much appreciated.
