I am pretty sure your 1946/1941 vise uses Acorn nuts. They added the cutout for a wrench. If your hole center line is less then a 1/2 inch then no room for swivel locks. The picture you posted has a issue with the center 1/2 dia pin that locates the base to the Static jaw support.
5" lock downs are much bigger and use the 5/8:11 thread on the early vises and 1" dia lock downs on the newer vises instead of the hex locks.
Share your date stamp pic's on the date stamp post. http://www.garagejournal.com/forum/showthread.php?t=269079&page=18 Bluebolt would appreciate it.
Thanks for the info Kevin. Yes I noticed the issue with the center pin when I first saw the vise as well. I was worried there could be a crack where the pin sits. Luckily just the pin is missing.
