For what it is worth, both of my 20 ga. repros measure 4-15/16.

Which is the earlier type label? Or, were they used inter-changeably throughout production?

The all gold label is from a case that houses an unfired SSS, the green/gold label is from a case that houses an unfired SCC. I believe the SSS preceded the SCC, but I don't think that means anything in determining which is the earlier label. I have to believe that the green/gold version is scarce, do any of youse have another one like it? Maybe it was a special run intended solely for die-hard Packer fans. ;)

Hmm. Might the second label have some corrosion of an original gold finish?

No, it came out of a collection in California. :)

Three years later, I have come to the conclusion that the 4 15/16" butt 28 gauge Repro is a rare bird, more shootable than the smaller butt 28 gauge, and will become a cult gun in the future, coveted by collectors and shooters. Anything in a Repro that is different and rare will attain collector value. Anyone out there have a big butt 28 gauge to sell in this depressed market?

I like big butts, and I cannot lie

Just like same gauge Repros may have different sized stocks as shown in this thread, there's currently a 28ga. Repro listed on GI that has a brown colored canvas & leather outer cover than the usally encountered tan colored C & L cover.

Yep, they're not all the same . . . This is the first and only brown colored C & L outer cover that I've seen. How about you?

After readig these posts, I decided to check my 28GA reproduction buttstocks. Both the straight grip and pistol grip measured about the same as Heff's.
