Sunrider, you are selling stuff you haven't examined by yourself? You don't know if the seats are absolutely useless or in normal state? I understand there's a risk in buying things from auction without seeing products by yourself, but buying something that even the seller haven't seen....really dangerous. Something like 1000-1500 US$ might be still suitable offer though with risk. Stidd seats are very technical and require a lot of special parts for refurb, so if you want a proper seat, buy new one. For some kind of like "project" this used seat might be suitable.
Tango, handles you see are just grab handles, nothing more. When you drive VERY fast your crew need them. The components in Stidd seats and ejection seats are similar, I have worked with fighter planes (including F/A-18) and Stidd seats, so I have compared the systems by myself. It's not just imagination, the feeling in the both seats are also pretty similar: when bound tightly, you know you soon will go fast!
