Hello, When I was a small boy my Dad had a big box of bits that were the makings of a Cooper race car. This was back in the 60's. Amongst all the race car parts was a wooden crate with an engine in it. I was intrigued by the crate with Triumph stencilled on it but over the years the Cooper parts disintegrated or were sold. Like many young idiots (I was 12 or 13 I think) I took the engine out of it's wooden crate and wondered what sort of go kart I could make with it. Drew up some plans and then got distracted by an easier lawn mower project. Unfortunately the crate got lost, but I have kept the engine ever since. I used to have a T120R back in the late 70's and always hankered after a Triton. I had an engine and gearbox, but couldn't find a Slimline Featherbed frame at the time, so that project never happened. I don't think it has been run except on the factory test bed. I'd love to know when it was made (I'm hoping in my birth year of 1957). Here is the engine number. Could anyone tell me something about it? I'm sorry about the yellow over spray - that was from a kart I used to race in the early 70's.
1950 to 1962 Pre-Unit 500 & 650cc Engine numbers had a prefix indicating the model type along the lines above such as 3T, 5T, 6T, T100, T110, 3TA, 5TA etc. This was followed by a number from the list below. YEAR – Pre-Unit 500 & 650cc 1950 – From 100N 1951 – 101NA to 15808NA 1952 – 15809NA to 25000NA then 25000 to 32302 1953 – 32303 to 44134 1954 – 44135 to 56699 1955 – 56700 to 70929 1956 – 70930 to 82799 then 0100 to 0944 1957 – 0945 to 011115 1958 – 011116 to 020075 1959 – 020076 to 029363 1960 – 029364 to 030424 then D101 to D7726 1961 – D7727 to D15788 1962 – D15789 on 1946 – 72000 1947 – 79046 1948 – 88782 1949 – 100762
Here's the whole link https://www.tricor-andy.com/triumph-dating-information/ Not sure what the x means
Thanks for the info. It looks like it was built in 1957 and that would be consistent with what my Dad said all those years ago. I think the X means that it was never fitted to a bike - it was built as a spare engine.
