It does look like an M-2! Great condition from the pictures! It is an amazing razor with the TWINs. If you have any less good injector blades, you'll want to insert one of those before the TWIN blade. It looks like there is a blade guard feature on your M-2. I thought it was unique to the M-3, but there is a finger knob on the bottom of the razor just like on the M-3. Very interesting. Nice find sir! I hope you enjoy the TWINs!
Thank you! Yes that is a push-up deal that raises the guard in front of the blade. Thanks for tip on preloading the blade, will do.
