Hi there,
im in the process of restoring our rotorvator that we have had in the family for about 50 years ,we used it alot back in the day but haven’t used it for a while now ,the engine was rebuilt by my uncle about 30 years ago ,he worked a the villiers factory in Wolverhampton at the time before it shut down ,He put a new engine shroud on it ,so it has no serial number to go from ,i have took pics of it for you to have a look at ,also im missing the original air filter assy and the lever that fits on the back that i think controls the depth if any body has a spare ,thanks wayne
