Hi, I hit upon this forum by coincidence because I was doing some googling for Ransomes lawn mowers. In the '50s and '60s I have mown the lawns around our house near Leiden, the Netherlands, using a Ransomes 18" Minor Mk 5 which looks quite similar to the Mk4 on the pictures. This machine was purchased new in 1952 and was used during almost 20 years. The quality of the mowing of this little machine was quite goood compared to lots of other mowers, in particular because of the 7 blades on the cylinder rather than the usual 5. This made the blades very hard to sharpen because the cyliner would not fit onto a mechanical sharpener. The job had therefore to be done by hand. I think I still have some 8mm film footing of the late '50s with me on it while I operate the machine. All I have left of this machine is the copper plate with the type and the serial number on it. That is why I am sure it was a Minor Mk5.
