GB Completed Sales,,, there are Zer0, I like to watch for them. There haven't been any offered up for quite some time.
With that all said,,, it does seem they do get offered up in waves.
My opinion, when some see a gun sold at what is considered a "crazy price" then others want in.
I paid $850 for my LNIB/ keeper in 2012.
I bought several No. 1's when they were offered in 2017 ~$1350, since then I have sold a few @ $2k, currently there bringing $2200-$2700.
There were a lot more No.1's built vs No.3's,,, and they are not making 3's in any caliber any more.
True 3 is not the quality of a 1.
The 3 has a 22" barrel vs 20" barrel on the 1.
I actually prefer the 3 over the 1.
The 1 is one short stout firearm, has a heft to it.
The 3 has better balance and lighter.
Not knocking the 1, just preference,,, mine.
