Hi,
Looking for informations about the evolution of IMO number and previous identification numbers in Lloyd Register, I note that in LR of 1930 to 1940 (site http://www.plimsollshipdata.org/) , every year the ships receive a new and very different 'number in book'.
Hereunder, the 'n in book' of each first ship of the LRs :
- LR 1930-31 : n63001 (the last ship is n83333)
- LR 1931-32 : n13001
- LR 1932-33 : n56401
- LR 1933-34 : n20201
- LR 1934-35 : n70701
- LR 1935-36 : n19601
- LR 1936-37 : n69801
- LR 1937-38 : n19501
- LR 1938-39 : n69001
- LR 1939-40 : n19001
Please, does someone know the reason (and link) of so various first number each year : for example n13001 in 1931, n56401 in 1932 ?
I thank you for your attention.
Regards, Yvon.

Yvon, I recall that the register just allocated a sequence number for each vessel each year in the order they appeared in the register. Why change the starting number, I don't know!
