The Lincoln in the photo is RE405, (not RF409 or RE409, which was sold to Argentina in 1947). The fate of RF409 is at present uncertain but it wasn't one of those sold to Argentina. Somebody else, as well as me, got confused between RE405, RF405, RF409 and RE409.
The J2M was never given a Type number designation! If it had it would have been Navy Mitsubishi Type 2 Land Fighter. The long designation that was given is plain Navy Mitsubishi Land Fighter Raiden. Or are you talking about the Type 5 Cannon? Type 5 cannon - Wikipedia.
