Help identifying old rotovator

Our community garden has inherited an old rotavator. It has done a great job over 2HA of compacted land just given to us in Edinburgh. There is nothing on the engine or body to identify the make /model, although there is a plate with the name of the distributor in Essex. I have tried to locate them but no luck, guess they do not exist anymore. The plastic starter pulley has just broken and I am looking for a spare. Can I post a photo of the machine on the forum to see if anyone can identify it? This will help me to get the spare part and maybe a manual too! Thanks.
