As bsms said, Syd Hill isn't making saddles commercially anymore, although there are probably still some out there. They did make a relatively wide one too. My Syd Hill fits my mare's almost 9" gullet.
The traditional stock saddles are basically a Dressage style tree so you won't get as much weight displacement as a well fitted Western or UP saddle (or variations that use those type of trees)
Also as bsms said a stock saddle is not necessarily "light". On average it might be few lbs lighter than the average western saddle and a few lbs heavier than the average UP saddle, but there are few absolutes when it comes to saddle weights.
On my stock saddle if I dump the brass stirrups and leather stirrup straps for nylon straps and synthetic stirrups I can get the weight down few lbs to the low 20 lb range, but for any more I'd have to cut out the sweat flaps and cut out or shorten the outer flap significantly. Stock saddles have more flap leather than any saddle I know of, but I've never seen the need for it.
It your wanting a light weight saddle and looking at an authentic stock saddle you might want to look at some of the endurance saddles (Saare, Stonewall, etc....). While they're not low cost you can still get them for less than a authentic stock saddle.
Whatever you get make sure you get the right fit. The tree fitting properly is the most important part of the saddle.
They're always going to be bigger and stronger so you better always be smarter. (One of my grandfather's many pearls of wisdom)
