My first double was a gussied up variant of this very design - a Savage Fox Model B. It was unnecessarily bulky and swung like a 2x4. However, I was a novice and I shot it reasonably well.
It is/was the worst gun of any and all action types that I’ve ever owned when it came to reliability. It broke down in the field 4 times during the time I had it. However, each time this happened I set out to fix it myself. This turned out to be the spark that started my foray into amateur gunsmithing. It also was where my tastes evolved to reject semi or full beaver tail fore ends in favour of splinter fore ends. The stark comparison between that gun and your average British or Spanish boxlock or sidelock conclusively made the case for straight hand English stocks for hunting rather than pistol grips and even Prince of Wales grips. The same comparisons cemented the value of a well balanced gun.
At the time, I was an American-made guns collector and shooter. I owned a graded Ainsley H Fox (touted as the best gun in the world), a Parker, a Baker (who designed the original Bakers, L C Smiths, and Ithacas if you’re not familiar with him), a Lefevre, a Browning Citori, a Steven’s 311 20 ga, a Browning Superposed, and even a Tobin. I’ve since sold every single one of them except the Baker and it would be gone, too, if someone offered me what it’s worth.
My collection now features British guns including a WW Greener and Spanish guns such as AyA and Arizaga. Incredibly even to me, I have a relatively new American double - a Savage Fox A Grade in 20 ga, which is made by CSMC. They are not your average American maker. Even so, if I wasn’t so poor, I’d far sooner have bought a round action Dickson or a MacNaughton.
So, have fun fixing up the old girl - you have nothing to lose and a whole world of knowledge and fun ahead of you.
