I purchased mine from "Allegheny Trading Company" which was the fore runner of Centermark. Been shooting it for 20 years now. I have made a couple of minor repairs to the lock over the years, but, this fusil has served me extremely well over the years, and it still looks and shoots as well as the day I bought it. The only modification I have made over all this time was to equip it with a sling, and a silver thumb spot with my initial. This weapon has served me well in all weather and circumstance for many years, and I consider it to be the ultimate as the one gun for all purpose for the hunter. As to the potency and effectiveness of the .62 Tulle, mine has taken a host of small game, turkey, deer, and boar. If I could have only one gun, it would be the Tulle.
