Just flipped through "possum, clover, & hades, 475th F/G in WWII" by schiffer publishing. In the back there are several photographs of MacDonald's various "Putt Putt Maru."
the first putt putt looks like an olive drab J-5 or early J-10 because the wind screen is rounded, ie lacks the one piece bullet proof windscreen. this 38 looks nothing like MacDonald's much published photos of the traditional putt putt maru.
The second is a natural metal J-15 which looks similar to later putt putts and looks like the yellow trim is missing.
the 3rd putt putt, 38L-1 44-24843 looks like it has the yellow trim around the black painted section that the victories are contained in.
4th putt putt 38L-5 44-25643 looks the same as the 3rd one
5th putt putt 38L-5 44-25471 looks the same as 3 and 4.
