Unless you absolutely had to, I wouldn't personally sell either, but If I did, I'd keep the 66 myself.
As a comparison, I have a S&W 57 I bought way back in the early 1980's that's a custom shop tuned 8 3/4 barrel 41 mag everyone said to keep un-fired. Well 14 deer later and many many woodchucks later it still has great value and it has feed me well and gotten rid of many wood chucks on my property .
In the condition mine is in and what un-fired ones fetch, there's only about 350 bucks difference,,
so, was the 14 deer worth the 350 bucks difference in value in my case???
Oh He** YA!!!
