Hi Mowers and Mod Gadge,
I must admit that the Robin Engine kinda looks a tad lost on a 24 inch Queen doesn't it ??
The Queen was purely designed for Cricket Pitch, Tennis Court and Golf Course Greens. She was no domestic beast that's for sure and it certainly requires two very strong men to lift her.
Looking at the ID plate I feel it was made around the mid to late 1960's. Sadly most of these have found their way to scrap as there are many more modern long bed ride ons that cut a much wider width and being what it is they don't lend themselves well to being handed over to a domestic user.
I'm not sure what your intentions are but please don't let it go via the way of the Dodo.
Cheers,
BB.
