Marples Ridgway Tennon saw

Bought new by myself in Gordons Tools,Long Street,Cape Town about 25 years ago you can see this saw has done good service.I wanted the brass backed saw over a plain metal backed as the extra weight of the brass adds to the power of the cut,it looks nicer too.These saws were an expensive item back then,I can find very little mention on Google of Marples Ridgway now.
