Machine number 2950A is a series one model, see photo below, and was sent to agent on 12/10/53 and delivered to Milnthorpe Grange, Sandal, Wakefield on 8/12/53. More information about Monrotiller can be found at Monrotiller Information
The engine number would suggest it is a Mk12.
The original engineering drawings for Monrotiller are held at the Museum of Emglish Rural Life (MERL) in reading.
I have copies of owners manuals and parts books.
