Title: Can anyone identify these gems?
Post by: Robert Zambelli on December 19, 2023, 07:28:16 AM
I picked these up at a swap meet around twenty five years ago and recently discovered them while cleaning out my stuff.
Paid $15.00 for the two.
All I know is that they are Bantams.
The one on the left, S/N 024672, has a modified/updated case as seen. May have been converted to glow.
The one on the right, S/N 0017683, is obviously spark ignition.
Both appear new/like new.

So, what's the story on these? year? Displacement?
Any information would help.

THANKS, Bob Z.

Bob I don’t know tons but I have two and they are .19s.  They made the cases from magnesium (dark color) and aluminum.  They were good engines in the day and very popular for A class FF.

One of mine on my 1940 Megow Aero Champ built from an original kit.

Hi, Dave - thanks for the reply.

I'll try and find an OTS plane suitable for the spark version.
Should be fun!

  They came out in 1938 with a sand cast case that was a .164

   In 1940, they came out in natural metal fins and it was a .192.

   In 1946 they came out with black fins and .199.

   All were spark ignition. You can see the cam on the one without the timer.
