British Army Artillery Alidade / Clinometer in Leather Case. The Alidade / Clinometer is in unused condition with all parts.The case has some marks and the inside felt lining at top has come away due to poor storage.The only information i can see on the Alidade / Clinometer is very faint and looks like No.965, Date.1919  and Casartelli & Son. Manchester.  Please see pictures for condition.
