The Paragon glass was run at the correct size. Period. Our panels are cut to the official Bally size from that era (28.5" x 25.75"), which applies to all glasses from that period, and thus all the Bally backboxes. Paragon was no different for us.
Here is another instance of one single case of an odd situation (at the user-end) creating a tempest in a teapot, where quickly the implication/impression to everybody tuning into this turns to "the entire run of Paragon glasses were the incorrect size". Which I doubt was even the OP's intention.
Seriously though, in 9 years we have only run ONE incorrect glass height (Eight Ball, back in 2007) which was 1/4" too short. Ordered the correct size with the glass factory, but they delivered as 25.5" tall (instead of 25.75") and it got through the entire production without notice. Never put a ruler to them back then, and always assumed an error at a factory on the scale of 200+ tempered panels delivered would never be screwed up. Plus the artwork centered fine when silkscreening (no red flags). Wasn't until weeks after release, after over 50 sold and shipped, the first customer pointed out it didn't reach into the top of his backbox. We ended up easily selling out of that glass within a couple months, regardless. Only a few others sent emails asking many months later. All of those with fitment trouble (ability to fall forward) were able to use the glass simply by using some specific trim tricks. For most, the shorter glass still fit *without* trickery, amazingly enough.
Rest assured, since then, we check the blanks upon delivery, right from the crates. Every time. Paragon definitely was done on 28.5 x 25.75 panels. Or it would have never made it onto the press.
In looking at the photos provided by the OP, it seems that our glass is indeed an oddball one. I can't imagine what else it could be. I just measured mine, and it's a solid 25.75" tall (see photos below) - just as seen on the tape measure of the OP's original. That one repro must be stunted, where likely the factory scored the sheet shy of target, and snapped it off there. Since the artwork is a fixed size, with an equal clear border all the way around, I'd be curious to see the bottom edge of his glass. If it's 1/4" too short, that would mean the artwork would have to be touching/spilling-off the bottom edge of his glass (because he seems to have clear edge on top, left, and right). If the art touches the bottom edge, definitely a single oddball glass from the run, as you can see mine is not like that. His artwork would HAVE TO be chopped off on his (just look at where the 25.5" mark lands in my photo). Is it? I'd love to know. Then I have questions internally of how that wasn't noticed and got packed.
As for thickness, all our panels are 1/8" tempered (as stated at the top of our backglass page) - regardless of what the originals were (as we all know, many variances of thicknesses, tempered and plate, were used back in the day). CPR sticking to one glass stock has to do with several constants: the significant difference/trouble in trying to temper the thicker glass (the factory recommends against it, as it exceeds their tolerances for guaranteeing even tempering edge-to-edge). Those original "thicker" glasses were on plate anyway. We're never using plate. It sucks. It breaks easier in shipping. It can hurt people if they tripped with one. Also, all our jigs, press, and processes are based on 1/8" glass stock. Also, weight for shipping is considered for our shipping rate.
In the future, if anybody has a query of discovering a potential run-wide error they *think* they have discovered, especially one unspoken nearly half a year after sellout (and that should be telling), take a moment, make that query with us as a direct PM and communicate your case. Before heading to the forum(s). Then we can take a look, see who's got what going on, and determine if a real runwide error or single error is going on. If one simply takes it straight public, declaring or insinuating that based on their piece, an entire CPR run contains an error - trust us, that is what people will follow suit and assume. It gets yucky (yeah, for us). Plus going directly public can go two ways: a) correct, you are a sleuth and master b) pie in face. Plus going directly public leaves us in the dark, and we don't know what you've found. For me, I would have never seen this discussion, had I not been directed to come here by somebody else (and it wasn't Stu). It was one of our regular customers who was concerned. This time, it was quick. Sometimes I may not find out until days/weeks later - then threads have bantered on deeply, and by then it's almost too late to come on and explain/correct/show and change dozens of minds to another viewpoint.
At least on this one, I hope people can trust that Paragon was produced at the correct size. The OP's glass is an oddball if it's truly being measured correctly (or are differing trims confusing things, etc). That bottom edge will tell the tale. I don't know completely. Had we had this discussed back after purchase, during the active days of it in stock, an exchange could have been done immediately. Now we don't have any more. I welcome a return and refund (no problem) if the OP chooses to go that way. But I need to be contacted

Please forgive Photo #1, as the parallax of the camera view doesn't allow a straight view of the 0" point or the 25.75" point without looking straight down (as in pictures 2 and 3). I just wanted to illustrate I wasn't doing anything hokey with the tape measure.
