If you want to talk with a dealer who knows and speaks very highly of the push forward design call Kirby Holt at Vintage Doubles. He shot one several years for his personal use I remember. Often he has a few on hand and his evaluation of guns is very complete.
Like I said I had an Adams push forward under lever that I really liked but the barrels were scary thin and by the time I bought it Teague was not taking on anymore lining work. I bought with the intent of having them line the barrels to save the Damascus pattern which was as beautiful as a fine burl stock. I so wanted to keep it I almost had Briley fit a set of 20 tubes in it but that would have destroyed the balance of the gun.
