Matching number Jowetts

[Keith Andrews]

What is the significance of a Matching number Jowett?
By this I mean a Jowett, that has orginal engine block, gearbox, diff..serial numbers all match...basically orginal steel body parts, hand books etc.
The definition I have found does vary greatly between countries, car clubs, and manufacture (make) of cars

Are there any giudelines for Jowett.
What Difference does this place on market and insurance values.
EG
I have a 'matching' numbers 69 Camaro.
All body parts panels stamped with factory serial numbers are orginal, block, trans, diff..other parts that wear out are replaced with correct parts with correct part #s..and if this is not the case the orginals are stored safely...orginal warrante papers, handbooks, tools etc etc
Insurance valuation is close to market....non matching numbers for the same car means around the $NZ 45,000 ...with matching numbers $NZ 65,000

I have a Bradford that the body, chassis..well just about everything is beyond resto...One of our far more knowledgable club members was digging thru it and found it does have matching body tag and engine tag...
Im unsure what direction I should take.
Should I resto another project and use these tags? doesnt really seem honest thu

So I need to know what the general international jowett comunity thinks, opinions or if there is a policy or definition????

Non-matching numbers may effect value if the car has some history, particularly competitive. Also body panels may show the car has had a bump. Jowetts were not very consistent in production so not too much store should be placed on them. However, matching halves of crankcases is a good idea, although I have put different ones together with no ill effects.

Just a few points with the UK and the EEC on the vin chassis numbers.
As most all cars are on the central data base there are requirments that have to be met for the MOT.

Colour, first reg date,engine size and type, correct matching numbers etc unless a visit from the DVLA will be forthcoming.

First the prewar only it seems have to have the engine plate with the nessasary details.

Good for prewar Jowetts as they do not seem to have a body number or indeed a chassis [vin] number any where on them unless i am in need of correction as my eyes are failing[need glases]

The Bradford is better with the engine plate and the matching chassis number on the bulkhead.

Now the Jupiter that is real class as a hand built car should be,every panel has the body number stamped that should tie up with the chassis plate on the bulk head and doc's.
The engine is stamped with the correct numbers as well in most cases.

In my mind any difference in the matching numbers on a car needs thougher checking and in the end will reflect a true lower value of the car and problems in other quarters.

My Long Four has matching engine and chassis plate numbers.

The chassis plate is actually on the bulkhead above the petrol tank, a little brass plate with the Jowett engine outline and the number hand stamped onto it.

I don't know about earlier pre-war cars.
