Looks like it is number 2743, Terry will be able to tell you when it was built. Bit of work on it and it has years of life left in it, they are so repairable compared to the newer plastic fantastic, made of the thinnest sheetmetal they can get away with and usually just last long enough to be out of warranty. If you have grass to cut on the new property, this machine is worth every cent you spend on it to get it mowing again, as long as you can turn a spanner and do the basic maintenance on it
