If the MAC is in good order, you have the makings of a bargin. I have a 16 Ga. MAC also. Mine has 70 MM chambers equivalent to 2 3/4, double proofed. Mine is unusal in that the barrels and receiver are made of steel, that seems almost stainless. As a matter of fact the barrels finish is a paint. I have no doubt that this is the original finish, as I bought it from a gentleman, whos deceased brother brought it back after WWII.
It is a pure utility gun, nothing fancy, but very well nade, and handles better that some 2.5K doubles I have handled. I would like to see some pictures of it if possible.
Postoak-
I could not have asked for more than to hear from someone who owns a MAC! Thanks for taking the time to respond. The MAC did impress me as being very well made in terms of fit(but as you say utility in finish), nice handling and light.
I am pretty sure that the gun I am looking at is blued. If a 70mm chamber, like yours I am very inclined to buy it. Your shotgun sounds like a workhorse with both the 70mm chambers and the double proof! The MAC I am considering did have some wear and tear to the wood (real nasty ding as I recall on the fore end). If this gun follows me home today (I still have to do some last minute coordination of the shoot today), you all will see some pictures.
