#1 Savage 1899A Short Rifle by the looks of the barrel length from the forearm and it's got a shotgun butt from what I see.
#2 Thinner barrel and pistol grip so I'd guess it was a Savage 1899 250-3000.
#3, can't really see the barrel band cause of the rack, if there isn't one I'd go with an 1886 33 WFC full mag cause of the shotgun butt on it as well.
#4 could be an 1892 or an 1894 SRC, I see a barrel band and it's shorter.
#5 is a double bbl shotgun I think.
#6 can't really say a model but it's Winchester with a full mag.
#7 is either an 1899H or an 1899F, can't tell which from that direction.
What do I win?
