Mike
Sorry I deleted my post while you were replying. I did a quick google and realized what he was referring to.
to go back to what Mike is referring to, I posted I'd never heard of them carrying a 45-55. all the references I'd seen were for the 45-70. After I posted, I google the info, then deleted my post.
In reference to hydraulic referring to them as a 45-55, is that proper terminology.
