Morton & Son, Glasgow.” 7” index bar set with diffuser, vernier with tangent and clamping screws, and reading glass, the apex with index glass and adjustment screw. Four index shades graduated green.

The whole contained within its original, fitted, mahogany case with compartments and green felt-faced buffers. The inner lid with National Physical Laboratory certificate of examination dated September 1919, bearing maker’s name and instrument serial no. “R334.”
The frame retaining most of its original finish, the shades, mirrors and telescopes in excellent, undamaged condition with good clarity. The tubes with some external losses and patination. The mahogany case with side-mounted internal instrument release button, swinging catches with safeties, flush fitting fold out transport handle and identification plate, retaining most of its original French polished finish, minor marks and abrasions. Lock and original key.

Heath was a prolific maker in the 19th and going on to the 20th century. These instruments are by no means rare – however the condition and completeness of this one make it unusual and set it well aside from most others.
Certainly a collector’s piece.
