Prof 7 #1 Posted February 1, 2020 (edited) I have a friend who has just bought what he says is a D4D. He's trying to date it, can anybody help please. Numbers on it show BC D4 524 6G 4941 7J 2329 I tried posting pics but they've disappeared. Edited February 1, 2020 by Prof missed bits off Share this post Link to post Share on other sites
ianoz 14 #2 Posted February 2, 2020 Sorry , i don't think that is a D4D serial number . It is possibly a casting number . On the earlier D4s serial number is on a plate on the engine and also on the top left hand side of the flat back area of the machine on a small plate . Number should be stamped in where the plate mounts , problem is , if the machine has rippers or winch fitted , serial number will be covered by them . Number should read D4D then series 85A or 79J this series number shows where it was built then there will be the actual serial number 1 Prof reacted to this Share this post Link to post Share on other sites
Wristpin 400 #3 Posted February 2, 2020 As far as I know the 7J D4 was built in the US between 1939 and 1943. The first D4D was not made until 1963 with a series number starting 78A. The D4D, series 88A, was being built in Glasgow when I worked there in 1965. 1 Prof reacted to this Share this post Link to post Share on other sites
