M1888/90 "A" Grade from Royal Tiger Imports - Same as "B" Grade?

I ordered a Mannlicher 1888/90 antique rifle from Royal Tiger Imports in their regular grade condition. I unbox it and show the condition of this example. These are supposed to be better than their B Grade rifles listed on the RTI website, but I'm not certain if this example is actually any better than most "B" grades. RTI is a good place to pick up some military surplus rifles, but how does reality match up with their description?

This is chambered in 8x50R and is legally an antique in US gun law, so it was easy to procure. This is the second 1888 rifle I have purchased, and both of them have not really lived up to their respective grades.
