Here for sale is a fantastic maritime drawing instrument by Harling of London. Harling were founded in 1851 in London. This lovely parallel rule in original box probably dates from the early part of the 20th Century and is made from boxwood. Great collectors item or just a decorative piece full of history. 


Shows signs of wear and tear as it is old and has been used, but only adds to its character. Great decorative item which would look fantastic in any home or business interior.

Please look at photos closely as they form part of the item description.
