I just aquired a generally well preserved Plath-DeTeWe aircraft octant (assume built in 1942 since the ) including all accessories and the box. Since the octant has nearly no wear outside - execpt the area at clock winding house - and it carries no acceptance stamp on the plate attached to the altitude disc as well as no index correction stamped on the same plate, I assume it has never been finally delivered to the air force. This type was the standard German air force octant (sextant) during WW2, type ("Ger�t") 127-134-B-1 or also known as a SOLD type. Beside some other small flaws (due to tampering I assume) the bubble chamber is nearly dry (no bubble possible, only traces of fgluid visible). Has anybody done a repair (i. e. filling) of the bubble chamber and can give me some advice? If so, what fluid was used or should be used? Might compass fluid work (I used it in a Link A-12 with good success since I could not locate a source for Xylene here in Germany)? --~--~---------~--~----~------------~-------~--~----~ Navigation List archive: www.fer3.com/arc To post, email NavList@fer3.com To , email NavList-@fer3.com -~----------~----~----~----~------~----~------~--~---
