I think that it probably isn't possible to provide an exact date without knowing<br>
the detailed build rates for the individual months *and* the corresponding<br>
chassis/engine numbers. The only place that holds those sort of details is BMIHT.<br>
<br>
According to Clausager 72623 is a mid-production number. It almost certainly<br>
isn't a Longbridge car as the highest known chassis number (according to him) is<br>
50759.<br>
<br>
Here's a stab at the date: the entire second batch of Abingdon cars (the<br>
late-'58/early-'59 batch) ran to some 8806, going by chassis numbers. Yours<br>
would then be 3663 into the run (5143 from the end of production).<br>
<br>
On the basis of six months production run, about 1470 cars were produced on<br>
average per month. This would suggest that your car would have bsuggest that it<br>
was built towards the end of November.<br>
<br>
BUT you have to take into account ramp-up/ramp-down in production (in September<br>
and March) and also the fact that the plant wouldn't have produced much over<br>
Christmas/New Year; and that in the immediate run-up to Christmas production<br>
would probably have at least slowed. This means that production profile would<br>
have risen between September and November, falling back in December and then<br>
going back to higher levels in January and February before tailing off in March<br>
59. What we don't know is the actual extent of the variation in production. On<br>
this basis it might appear reasonable to suggest that your car may have been<br>
produced between the last couple of weeks in November and Christmas'58.<br>
<br>
You could cross-guesstimate the month by taking the date of first registration<br>
in the US and subtracting two or three months which would probably approximate<br>
the time between roll-out from the shop to arrival in the US. The time would<br>
vary, of course, depending on where it was delivered to and at what point the<br>
then-current US rules required it to be registered (e.g. on first arrival in the<br>
US, on delivery to the dealer, on sale etc.).<br>
<br>
Sorry not to be more helpful,<br>
