I like the way you have added the frame pieces with the body off. So much easier than the struggle I had to push 'em up from underneath with every thing else in place. Your photo does show the superb quality of the castings for the draincocks and associsted pipe work. The Brassmasters, to my eye, are much better than the Gibson version. One point that I have always considered to be not worth the efort is changing the axle boxes. Yes I know that the replacements have more depth but can you notice the difference in most views?
