This is a hard one to find. It is the 2" 32mm Research Grade Erfle that Meade sold during the 80's. Even harder to find is one which also includes the 1.25" barrel! You simply unscrew the 2" barrel and replace it with the 1.25" one. It cuts the apparent FOV from 65° down to about 55°.
It is in near mint condition. I do not have the original caps or box but will include a screw type bolt case.
