Hi PGW,
Firstly welcome to the ODK Forums.
Value of a Supercut ??? mmmmmm, all I'll say is that they are only worth whatever someone is prepared to pay for one.
They certainly don't have a following like the Model 45 does, so from that point it's near on impossible to put a figure on one.
There are still quite a few laying around in old back sheds of homes and also bowling clubs, but none of them are used really due to their awkwardness of use compared to more modern machines. They certainly aren't a great domestic machine due to their "in / out" style drive clutch set up. basically they were designed to be a straight running mower for tennis courts, bowling greens and cricket wickets, but definitely not for going around tight curves and dodging trees and plants etc. in the average home garden.
After saying all of the above and you're probably going wonder why what I'm about to say is so complimentary, They are probably the "Best" cylinder cut mower that SB ever made, but that's taking it's design into account for what it was designed for and not what many of us have tried to adapt it to do.
Anyway yours is a bit of a strange unit as it's got a Queen / Model 65 style belt guard fitted which never came with these, so that may be someone's after sales add on. It certainly looks as if it's had a repaint at some point in time and maybe that's when the cover may have been done. Also it's had a TWM Chonda engine replacement fitted which is a Chinese cheapy Honda copy. Regardless though of that, if it's looked after and regularly serviced you'll find it will serve you pretty well for many years to come. The alloy rear roller ?, absolutely no idea on that one.
Just a thought, it may have originally been a Electric unit that's been converted to a petrol powered unit, but I'd have to see a few more overall photos of the machine with that belt cover open opposed to the close ups you've supplied (which are great BTW) Electrics though normally only had one lever and that was the drive as the reel was engaged by the electric power switch on the mower.
Apart from all that I'm really outta words, but one things for sure and that is this one is rather unique and I'm not 100% sure about it's originality.
Cheers,
BB.
