This 1950 from the East Coast (Philly Area)
This 1949 from the West Coast (North West)
Sweet 49ism....a blank shroud and nipples!
The 49 must have had the same painter as my "Dirty Nine"...all blue frame, oil tank, sheet metal, etc.
It's funny I popped a blue '50 pan up a couple years ago...popular color I guess...
