Does anyone know specs on original bumperless no grommet version of the POG OS

Hi,
Just wondering if anyone knows weight, swingweight and balance for the first version of the POG OS - without a bumper guard and no grommets.

I have only measured a single NOS POG produced by Fansteel, the true "first version" that was made from 1978 to 1979. It weighed 377g strung, had a 4 pt HL balance, with a swing weight of 374, and a flex of 67 RA. These are as close to 'as-shipped' measurements as one is likely to get today, but they are not typical. In fact, there is such a wide variation in specs among used grommetless POGs that I believe they were never all that uniform even when they were factory fresh. Bear in mind that POGs were not shipped in L M H weights; they were supposed to adhere to a single set of specs!

The lightest unit I've encountered weighed only 350g strung (a late Grafalloy), while the heaviest weighed 384g (an American Sports Equipment). The average was somewhere between 365 and 370. Balance ranged from 3.8 to 8.7 pt HL, averaging out to 6-6.5. Swing weight went from 326 to 374 (the NOS Fansteel above producing the highest reading to date), with the majority in the 340s and 350s. Flex of visually intact units can be as low as 48 RA, and as high as 67 RA (the NOS Fansteel again), with most units hovering near 60 RA.

This high degree of variation is not unique to US-made grommetless POGs, as it is also present to some extent among Kunnan-produced grommeted examples, even though Kunnan used a completely different method to make his frames. My assumption is that the relevant QC specs in the production contracts supplied by Prince were not overly tight when it came to frame weight and balance.

i have a few that are really heavy and have one that is interestingly less than 12 oz strung. i dont have their specs though.

Here's the specs of mine.

Weight: 357g
Balance: 32.7cm
Swingweight (TWU method): 349 kg·cm²
Yes, that's the one I've got, including power pads. Thanks also Sanglier for the detailed information and Joah310.

Reason i'm asking is that TW said the POG OS Classic they'll be getting in is a copy of that original bumperless, grommetless version and quoted a weight of 12.9oz. I dont have mine with me to check but that original has been my favorite for years and I still use it in competitions. I used the later models but in comparison they all felt too light and the balance was never right no-matter how much I tinkered with weight. Also, i prefer the short handle and they said the re-release would have that.

I didn't measure it but bumperless-grommetless version seems to be of thinner beam than the later ones. Another reason I like it.

I was just thinking the same thing today when I was looking at my bumpless/grommetless POG OS and 3 stripe version. Didn't bother to measure it but there is a noticeable difference in thickness which might account for the flexier feel of the original version. Either way I do prefer it. Although that said, I feel that I get more spin out of my newer 2005 Tour version but more touch/feel and heft from the original.

18mm for the grommetless, 19mm for all others.

That one looks a lot rounder than the other POG1s I've seen floating around.
Yes, doesn't seem to have that original tear drop shape. Not surprising though and I'd doubt if they still had the original molds. Been a long time since they moved to the rounder head.

I'm interested to hear about the balance. The original was heavier than the newer versions but i always found it to have a better balance for volleying. Have never really been as comfortable at net with the new ones. But like someone else said, I get more spin out of the newer.
