Re: 1991 R540LTD neck pocket stamp

And thats not "1H" thats "IH". I haven't sorted what the "I" could possibly be yet, but i know it has something to do with the heel, because on the all access neck joint models, theres no "H" stamp at all but theres now an "AA" stamp instead.
01R instead of 540R though is something I'll have to bake my noodle on for a bit....
