Bill, Yes I collect some of them. I have several off of the SP at Cannon on the Cal-P, some off the Santa Fe in Fresno and some from the McCloud in McCloud. Shannon WP LIVES
Just from the Milwaukee Road...... I have a bag full of spare GN and another full of spare Milw........... Know of a price guide on line? There is one decent site. But it does not have prices. I really don't want to buy a book for just one RR. Boxcab E50
I have a few, picked off the Santa Fe's Paris-Farmersville (TX) line, and some I got out of the former MP (originally T&P) yard in Paris. They're not in the best shape, but the heads are still readable.
