The round beam (M type) was available in Ireland, as 12" and 14". The old ones had the Hydrien Bodies 1965 to 1975 (no Shin Piece) These were also painted yellow and sold branded as Bamford. Later ones had No 3 bodies 1975 to 1983. I doubt any were sold here with No 8 bodies (1983 on) as original, but could be fitted.
They had a trip kit available as an optional extra (coil spring)
This M type was replaced by the MZ type, which had greater under frame clearance (longer leg). Most of the M and MZ had (optional) Grassland skimmers fitted on the discs.
The Stenomat auto reset - flat leaf spring) was available in round frame and later with square box frame. Most of these had (optional) Independent Skimmers fitted on to the frame. There was also an ( optional) Trashboard available, which bolted to the top of the board, with two bolts
The Stenomat started out with Hydrien Bodies (no Shin Piece) No 3 bodies (Triangular shin with one bolt) and then with No 8 bodies (long shin with 2 bolts).
The reversible was designated as the "E"
They then went on to Vari Width (I cant remember the letters, maybe MB for conventional and EB for reversible).
Then there was the Match Plough, o
r Competition Special, which was a kind of a 13 inch with spacer plates to adjust the width. These will be familiar to a few on here.
History lesson over, but all the books are in storage here
