Fender tag

Hello all.
Alaskan_TA, can you tell me what I may be buying from this fender tag info. It is a '68 Valiant Signet. I know that QQ1 is blue paint and a few other things, but I can't find info on what some of the codes are. Here are all the digits from bottom left to upper right: VH21 21 5 11 824 187463 2nd line: 4 3 8 1 H4X QQ1 B 3rd line 11 1
That is all that is on there. A pretty sparse car I'd say.
