Reference the piece in Grass Box No.112 'Successful Mower'
I have recently been discussing with a few colleagues the numbering on Gamages Champion range of mowers which were sold over at least a 30 year period, each having a Model No.
I was intrigued to see Thomas Gunn's Success No.3 & with a bit of digging can now ad a bit more.
In 1921 they advertised the 'Success' No. 2 with a similar style to the 1927 ad shown in the article, but also mentioned their 'Success' No.1 with larger driving wheels, the No2 available in 8in to 16in & the No.1 8in to 14in.
By 1933 they had reached No.33, but assume they have simply linked their numbering system to the year rather than having produced 30 other models in the intervening period!
