Great bike! Great find.
1938 makes it a little easier to find the parts.
The 38 chain guard is more common to find, the stem can be the reverse style as shown in the catalog instead of the putter stem, you can also go with gothic fenders with the initial tray instead of the deep McCauley that are harder to find, and you do not need the special drop stand and clip and can go with the side stand. Or you could go with early 38 and have all the hard items to find.
But it’s all just catalog pictures
