Hi Ty,
This is coming along nicely.
Comments:
[1] I think the Mohall needs context, dating (1948) and Laurence Hall's name. For decades, in public consciousness, the myth that Mervyn Richardson single handedly invented the rotary mower prevailed. To a great extent, that view still prevails: I think we were happy to not question that myth - with World events like the Opening of the Sydney Olympics presenting stylizes victa mowers as something uniquely Australian, as presenting the 'true' view - that the Victa was our gift to the world..
However, in the last couple of decades, there has been official recognition of the 1948 Mowhall as at least being an 'inspiration' for the late 1952 Rotomo. Your thesis attempts to 'set the record straight', in that it wants to go father than that conceded view - that both the UK and particularly the USA had examples of rotary mowers in general and domestic, lightweight, direct drive, petrol rotaries in particular.
[2] The other thing is the omission of mentioning the electric mower tradition. Does Cyril Thomas deserve a place in our history books? Was the Tecnico our first rotary mower? To what extent and degree should both Hall and Thomas deserve credit?
Cheers,
Jack
