Metters built the 8hp Frisco style engine from around 1911 or 12. I don't know how long production lasted.
The Friend copy that Patrick mentioned was a 2hp horizontal, hopper cooled. Metters called it the Nufrend. Production started at about the same time as the vertical, but continued as their spray pump engine into the 30's.
A very interesting quote from the 7 October 1912 Advertiser: "The most important addition to the firms long list of manufactures is their petrol engines. Finding that opinions are much divided as to the merits of the two cycle and the four cycle petrol engine, Metters Limited decided to adopt both types. If one wishes to see a real live engine he would be well advised to inspect the two engines running at Mile End."
We know they didn't have 2 cycles or 4 cycles, but we know they mean 2 stroke and 4 stroke. That is the only reference I have found for a Metters 2 stroke. Anyone have a photo?
The engine photo below was taken at Goolwa quite a while ago.
