WTB - 3ttt Saddle (Early 80's Vintage)

Looking for a 3ttt saddle of early 80's vintage. Not looking for NOS, more hoping for gently used. I've attached a picture of the type I'm looking for.

Thanks for your help! Image: https://cimg2.ibsrv.net/gimg/bikeforums.net-vbulletin/1600x1200/3ttt_089a0976db3acbc29f9fb1642d233e764b4f4f24.jpg
