This is an obvious question...

...but do we know that the 16mm version Puggo transfered has the same subs as the 35mm version? I assume they just did a straight dupe from the 35mm source, but since this was actually made for commercial sale and was re-edited, there is always the distant possibility that they re-burned the subs for this version, just as they did for the VHS versions. Was Puggo's 16mm dupe ever checked against the 1977 telecine bootleg? I just assume someone did, but I never actually saw this mentioned anywhere.

I've checked them against the telecine and they're a perfect match in positioning, you cannot make it out if it uses exactly the same font as the quality of the transfer is very bad on it but it looks very much like it and I would be suprised if they just changed the font on the 16mm, so I'm 99% sure it's authentic but it's a very valid question though. You can see caps of the telecine if you follow the link I posted on top of this page.
