YOST 465 Vise

Years ago I bought a Yost FSV-4 vise. Built like a brick commode, the "FS" means forged steel.. So last year I started looking for the 6" variety which would have been a FSV-6. Can't find one. All I can find is the ADI-6. So I contact Yost and ask what's going on. The good forged unit (FSV) was dropped because of "competitive pressure" and now all that's available is the ADI version (Ductile Iron). I bought a Ridgid F-60 forged vise.
