SOB in the store wouldn't ask the owner (consignment) if the seal had ever been replaced. They are notorious for disintegrating after twenty/thirty years. Stock had one or two good licks. Just not so sure about it. With a tune it will run it well over five bills. I might do a rebuild, myself, but it's kind of an expensive first gun to cut teeth on. And, get this, I used my 34 which I recently got from Howie (tuned by John in PA) to put two pellets into a paperback in order to check how hard the 124 might shoot. Certainly not as strong as the 34 but would give me an idea. That 34 actually is on a par with the 124. Just as good bluing, great trigger and the same cocking effort. Comes down to the 124 being almost the same thing except for a bit fancier stock. I'm having to think this one over hard.
There was also a cherry Geco (Diana) 6 pistol - BUT - same thing with those danged seals. Can't tell if they are good until you tear it down and, boy, those are not easy to work on. I think the rifle and pistol came in together, most likely as inherited goods. Therefore, no info available as to their being tuned or not.
Well, I need to sell stuff, anyhow. Will herd the ducks into a row over the weekend.
