As far as I'm aware my copy is the boot, but never been 100% sure, the sound on my copy is excellent all the way through and has the same number in the run out groove but can't see the 161 and squiggle. From where the record finishes to the label is approx. 6/8" and the run out groove is 5/8" definitely well below an inch whatever you wish to measure as the run out groove, I've always been lead to believe the boot run out groove was an inch. Had my copy for over 30 years and never been sure which it is, I've included pictures off both sides, hope this helps and maybe someone can confirm which mine is.
