I am trying to find parts for my Hamilton Vertical Card Compass. I bought
the thing, Model HI 350, serial no. 274, for my flying machine in 1982 from
Hamilton Instruments Inc Since then, Hamilton has gone out of business.



Instead of a normal whisley compass, this thing has a rotating vertical
compass card that looks like a directional gyro, but only 2 1/4 inches in
diameter. It is very steady and does not jump around like the normal
compass in turbulence. In order to make it swing, I had to buy a remote
sending unit or transmitter, and mount it in the wing. Works great.



I would like to purchase a new remote sending unit and the required 20'
cable for the new set of wings I am building, but I am having no luck
finding where to look.



Does anyone have any ideas as to where I should look or who I should call?



TIA


Based on my last experience with Hamilton many years ago, the last time
mine needed servicing, I think you'll be luck to find a working remote
sending unit. I don't believe they had any significant inventory; and any
that have been sitting on the shelf may or may not be working.

I have pretty much decided that when the one I have breaks, I'll probably
replace it with a SIRS compass: http://www.sirs.co.uk/aircraft%20light.htm
