Antique 24" Brass Parallel Rolling Navigation Ruler - J Casartelli & Son - c1900

Item is in good cosmetic condition for it's age, although it would benefit from a thorough clean & polish - see photos.  Case is missing on of the catch pins as well as one of the felt pads.  The left hand wooden wedge has also come unstuck.  Ideal light restoration piece.

Any questions, please ask.

Thanks for looking.
