Thanks for the welcome. I'm unable to upload pictures at the moment. It is definitely a Bonmow sometimes known as a Model 19. The serial number is BM0821* the * is an unclear numeral possible the bottom part of a 3 or an 8. The frame is iridescent blue which was the original colour although mine is some what faded. Does anyone know the official colour? It is powered by a 1/2 H.P. 4 pole (1425rpm) Crompton Parkinson single phase capacitor start electric motor. The drive to the cutter is by way of a chain not disimilar to a push bike chain on the left hand side of the machine. Drive to the rear roller is via a similar chain which is missing on my machine. The front roller is one piece metal probably from a Model 45. I think the original was a split wooden roller which I guess has disintegrated after close to 60 years! I would really like to contact other owners especially in South Australia!
