Vin replaced the old system of chassis numbers with a standardised format.As were some British ships If I recall. Victory herself was dis-masted. I'm not exactly sure how that would have played out viz insurance and lost prize money, but there was money somewhere I'll be bound. But it's also worth bearing in mind that in the ruckus after the battle, people would have looked after themselves- probably not the official version. Also long servers would have either deferred or stashed their prize money. Look on it as a sort of OAP.
where there any? Even coach builts had a record of a chassis number. I mean you could be going back to pre Great war
