The handle in blue is actually bent pretty bad so I’d like to make a new one.
Check out this thread for vise parts. https://www.garagejournal.com/forum/showthread.php?t=88292&highlight=vise+jaws.
Also I haven't found it yet but there was a guy on this forum that use to make and sell vise jaws on here.
The bolt for the swivel lock is a standard carriage bolt . The nut with the sliding bar is fairly easy to fab from bar stock. I've made several, I do have a lathe but it's not a necessity.
A lot of guys on the forum have good luck using an arbor press to straighten bent handles.
this thread has lots of good vise repair information:
