Hello friends. I'm looking for some help. I came into a set of steel old-style 1" medium Warne rings with 2 sets of steel bases, all new in the factory plastic. Bases 6051 and 6052 are identified as for a Remington 700. Bases 6044 and 6045 are not identified and I have not been able to figure out what rifle(s) they are for. In the past I have done a number of Google searches and what I remember I found is that Warne changed hands and the identification number system changed with the ownership. Can any of you guys help me with this ? Thanks, Hunter
