ITS A GMC NOT A HALLMAN SORRY!!!!!! GET IT RIGHT 
Thats right Paul, it's not a Hallman.
The USA built frames were known as Hallman's....

The UK models were known as HL's....

So it's really a HL replica, abbreviated to HL

Nice job Marc, has it been fired up yet?
40 odd hours to build you say Marc, that's odd, according to my records it was closer to 40 months

The originals went together a bit quicker....
