I have attached several photos of my rare (and therefore very valuable) variant of the SNO-T.
The engineering was very precise for the mounting of the telescope as the feeler gauge shows a clearance of only 0.25mm between the telescope and the index mirror mount. The external diameter of the telescope is 50.65mm and the clear aperture of the objective is 40.19mm.
