An english eptzval lens from 19th century engraved.

Brass barrel is in nice used condition with shiny patina and few marks due to age. Rack & pinion focusing system works as it should. There is a waterouse slot (width 35mm) and 4 waterstops are included.
Front achromat has a small chip on the edge (see attched picture), could be covered by india ink. Rear lens is complete (2 glasses separated by metal ring). Original leather front cap is included.Original brass mounting flange is included. Diameter at mounting thread: 57mm. Outter diameter of flange: 83mm.
