I've got a Precision Aviation Vertical Card, magnetic compass, a P/N PAI 700 WT. It's 2 3/8 by 3 inches. Yeah, I know, per Dougie, I'm supposed to put a picture here, but I've always had a heck of a time trying to make that work.
Aircraft Spruce says $335 for a new one---how's $150 plus shipping grab you?
I can send email pictures, no problem. If you're within a 2 hour RV flying radius of Atlanta, I can just fly it to you.
