RARE! Antique Homebuilt Two Cylinder Opposed Piston Engine. WILL IT RUN?

What an oddball! A friend gave me this engine to get it running and see how it was held together. It is one of a kind and someone has a lot of blood sweat and tears into making it. I’m assuming its from the 1940s based on how its built. and should be cool to see it run! Hope you Enjoy!
