This partnership quickly dissolved and in 1792 Nathan joined Jedidah Baldwin in business as Baldwin & Storrs. This partnership lasted until 1793 when Baldwin moves to Hanover, NH. After that Storrs operated on his own for the most part. Nathan Storrs had perhaps the broadest range of engraving Read More...

Small Lietz Mining Transit – Nice Condition – Circa 1925

One of my favorite things about this little instrument – Lietz made the instrument so that it lays in its box rather than stands upright. A very cool feature in my opinion.   The optics on both scopes are good, with all cross and stadia hairs present (only the main scope has stadia hairs). The caps and sunscreens are present as well.   The transit comes complete with its box and tripod, as shown below.   Lietz Model 12 Mountain and Mining Transits that have Read More...

While there is some evidence of use it remains in remarkably good condition for Read More...
