Note:

This telescope is in good working order with clear images.

The main barrel tube has been dented in places and the dented areas have been repaired, so that the performance of the telescope is not affected, apart from the cosmetic appearance of the tube. The original leather bound covering is complete and in reasonably good condition, with normal wear and tear to its surface.

All internal lenses have been cleaned and the telescope gives a very clear image. There is a small chip on the front lens near its edge (as shown in the last photo), but this is is not visible when looking through the telescope and it does not affect the light transmission or performance of the scope in any way.

Please see photos for further details.

This item has an important historical value as well as for practical use.
