Thanks for this photo. I would normally call your .30-30 action a "Second Model Utica". Alloy guard with slim trigger. However, two things prevent me from doing this with your rifle. Now, assuming the assembly numbers match and because of the color casehardened frame, I believe when Savage moved production from Utica to Chicopee Falls, the already completed actions were barreled and color casehardened at Chicopee Falls and Chicopee made barrels installed. I have no proof of this. It is just, to me, a logical guess as to why early, normally unmarked, blued actions from Utica, are color casehardened, with Chicopee barrels. Thanks again for sharing with us!
