Air Speed Indicators KM/H

Dear All, We have TWO airspeed indicators that have been stored for a few years. They came with our 2 seat glider but were quickly replaced because we use Knots and not KM/H. Both instruments were working properly when removed and were low-time. We are asking USD $185 per unit or $350 for both. I will be happy to answer questions. Shipping at buyer's expense.
