Yeah, that second one is refinished to the point of being bubba'd. I guess if they are happy with them it is their carbine after all.
My SinoBanians all look mostly like #3, though with the replacement stocks, some look decent enough:
To be honest, #1 is the first SinoBanian I got and still my favorite of all of them. #2 has almost zero bluing left on it. #3 is has a very nice original stock but unfortunately, a mismatched receiver cover, and #4 has a relatively well fitted replacement Alby stock.
