When I bought my glider a year ago there was a PZL Warszawa ll compass
that came with it but was not installed. Looking at it I found that ther
was no fluid in the unit. Looks like a nice little so I thought I'd
refill it an mount it. The problem is that I dodn't know what type of
fluid to use. The PZL website states that it uses "ligroin" but don't
have a clue where to find any of that stuff. Any ideas? Thanks

I just looked up Ligroin in a chemical engineering dictionary. It seems
to be about as non-specific a term as you can find. It can mean anything
from petroleum ether to kerosene as well as everything in between.

Airpath compass fluid is similar. Its a C10-C13 alkane, which sounds to
me remarkably like good quality kerosene or paraffin, so I'd suggest you
use that. Looked and smelt like paraffin too, when we refilled my Ludolph
compass with it last winter.
