Hello
At Springfield this year I found P2K Blue Box Chessie System SD9 (actually 3 I think). I sprung for 1 (regretting not grabbing the other 2).
In the parts bag are sunshades (prototype photos indicate B&O didnt choose this option), winterization hatch (installed on prototype), rock plow pilots, two bay windows (cant find any Chessie SD 9 with these), three small items circular in nature (steam generator details? prototype photos do not indicate existance), two side frame mounted re-railers (not installed on prototype from what I can see), and a piece of metal wire with a loop in it on one end and a 90 degree bend on the other (no idea what this is). The detail parts chart says yes to steam generators and sunshades, but the only photos I have found doesnt seem to indicate that is the case on #1840. #1839 has sunshades. #1831-1838 all have dynamic brakes. #1839 and 1840 do not.
