Pics added further down thread 
Bought new by me back in the day for loadsa money (I think it was £69.99 in 1992!).
Revolutionary saddle that was one of, if not THE first to offer multi-positions, and a longer nose for better seated climbing. I needed all the help I could get and it worked. Lower profile rear for hanging off the back on downhills too. Nice design especailly for the time.
Has seen only about 20 dry rides, condition is fantastic for an 18 year old saddle bar a scuff to each rear corner and two wee scuffs at the rear, nothing a little leather food can't cure. Pics to follow tomorrow.
Specs:
Titanium 6Al-4V rails
Super smooth leather top
On the left rear is the Wilderness Trail Bikes logo which reveals the consultancy relationship WTB has with Specialized.
On the right side is the Specialized Team Edition logo.
All logos present but pretty faded due to age.
234g
Pretty comfortable for a performance/race saddle, but I'm on wider perches these days and this ones pretty rare so belongs on a period showbike really.

The Specialized Prolong saddle is made nearly an inch longer in the nose than most of the other saddles. It is 11 3/8" long, tip to tail, without the added weight of a full length rail.
The return curve is 1 3/4" from the tip.
It is manufactured in Italy, by Selle San Marco to Specialized specifications. The shell is made of molded nylon, with anatomical depressions to fit added padding in needed areas.
The shell is covered with molded, high density foam padding, that is luxuriously thick on top, thinning on the sides and feathering into the saddle shell at the bottom edge.
The foam support is covered by a very smooth Black leather that is cut with care, and glued cleanly to the bottom of the inner shell.
The height of the front half of the saddle is cut shorter so the Prolong isn't as wide, producing less leg chafing.
The Prolong has two rail receivers molded into the shell at the rear and a front rail bridge that is a solid block, re-enforcing both sides of the shell at the nose.
