Fellow metal-philes. (Groan. Sorry, couldn't resist).
I ended up buying it from Online Metals with some other stuff. They seemed to be as good or better than others selling the same thing. Some are better for one material and a second is better with another. So rather than order from 3 or 4 different places I just lumped it into one that seemed to best price on the bigger ticket items. I did order some 1 1/4" x 1 1/4" 1018 CR off of e bay. That size of brass is just too much moolah for Scots Blood Peterson. Considered 12L14 but the cost was quickly out weighing the advantage. Besides, in 1.5" scale the 1018 steel will not be too bad to work with. Brass shore looks purdy though. Thanks for all your suggestions. I'll file them away for future reference.
