Anyone know how to identify a key profile?

So I bought a full replacement lock set from Classic VW Parts and would like to get the period correct OEM VW keys cut for it but I've no idea which profile I've been supplied with or how to identify that. Anyone done similar or know how to tell what's what?

Any help gratefully received, pictures of the new key as follows (I can post more if I'm missing an important angle).

Thanks all.

If it helps I bought an HV profile key blank for mine from Heritage. Have a read, this would suggest that an AH blank would also work: https://vwgolfmk1.org.uk/forum/index.php?page=topicview&id=mk1-golf-chat_2%2Fwhich-key-code-hv-or
