Richard,

    I was recently reading about commision numbers and so forth and I 
thought I might try to help. The number riveted to the dash is the 
serial number of the car, in this case being "G-HN5-UJ 458091-G".
The code being:

"G" - an MG car
"H" - car having an engine in the 1400 to 2000 cc range
"N" - a 2 seat roadster body 
"5" - kind of like a Mark designation, in this case a car produced from 
        late 1969 to 1979
"U" - car was made to North American specifications
"J" - the car is a 1979 model year

"458091" - serial number, in this case the 457990th MGB produced (is 
this a correct statement?)

"-G" - this suffix indicates that this car was assembled in Abingdon

As for the other number, I believe it to be the body number. However I 
think there is a mistake. Are you sure that the number is not 
"GU23T868542P"? If I'm right, then the translation is probably 
something like:

"GU23T" - rubber bumpered North American roadster
"868542" - assigned body number
"-P" - indicating 'body-in-white' and pressed at the Swindon plant

This 'body-in-white' meaning that the body was given a quick spray of 
white paint when it left Swindon and the final colour coat being 
applied in Abingdon. As for the original colour you have to contact the 
British Motor Industry Heritage Trust as Mr. Bert Palte suggested. 
    In summary I believe your car is in all probability what you have 
been told it is, but it may have had some front-end damage. Other than 
that the car sounds original in the sense that the info you provided 
does not seem to indicate that the car is made from a collection of 
used bits and pieces.
    I hope this has been helpful and as always I appreciate comments.


            Dave Hay  1977 MGB     still in storage :(

p.s. - All MGB owners should read "The Original MGB" written by 
A.D.Clausager and published by Bay View Books. The book also covers MGC 
and MGB-GT V8.
