According to the Cat SNID book the 7J started production in 1939 and the 5T D4 in 1943 and then the 6U @ 7U in 1947.
Between the 7J and 5T there were also the 2T series machines,7J 1939-1943, 2T 1943 to 1945, 5T 1945-1947. then they broke with traditionn and gave narrow and wide gauge separte serial numbers, narrow 6U series and wide gauge 7U series. 1947 to 1960? But I do know that the later D4C, 24A (UK built) started production in 1959!
Catsilver, I think this Cat SNID sales book I got from the dealer is mixed up a lot. It shows as you said the 2T coming out in 1943 and also the 5T coming out in 1943 and the 5T RD4 coming out in 1945 both starting at 1 and up.
Hi Martyn
Wendel's List show the following.....
1939.......7J1 - 7J1754
1940.......7J1755 - 7J4110
1941.......7J4120 - 7J7544
1942.......7J7545 - 7J9939
1943.......7J9940 -
I'm not sure what happened to 7J4111 - 7J 4119 probably a misprint.
I'm the proud owner of 7J2832W (W = Wide Gauge).
Thanks everyone.When I go down to see the machine I will post pictures of it.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
