Hi guys a bit random but you never know

my workshop engineering vice has broke its spring that locks the quick release its about 35+ years old as my dad baught it s/h 30 years ago atleast but had little use generally its a a big vice its not a record but it does say steel on it so its a good quality one

Does anyone know where i can get a new spring from or do i have to get one made which i dont mind if i have to as i know a place that makes springs ive never used them tho

Stripped it it all down going to get it blasted and give it a good refurb
i know now my odds are slim but u never know
