Gun looks honest to me. I would have been in the running if I knew it was up for sale. Just for comparison here's a pic of 12-ga and 20-ga/3 inch breeches on a 2-framed VH. Both 32 inchers. The 20-ga is stamped 4^11, a tad lighter than the one discussed here. Barrels actually weigh 4^4 and chambers measure a few thou under 3 inches long.
For those of you coming to the Northeast SxS two weeks hence, I'll probably have the Super 20 as I call her, out at the Bo-Whoop Long Range shooting butt. She does well at far off game and I want to try her on those targets. Stop by if you want to check her out.
PS I've taken a few turkeys using 20 gauge/3-inch Western Super-X papers, folded crimp with 1-1/4 oz of #4 shot. I'm now nursing an almost full box. Good to go for another 20 or so birds.
