Vintage MB century toolbox/ cart

[KLD619]

Looking for anyone that can shed some light on this box since I can't seem to find anything about this set up. I'd like to know a approximate value and possibly date. T thanks for any help. New to the site and excited to get to know the group and how this page runs.

I am out of town, so not where I can take a picture, but check the lower left front just below the tambour roll up door on yours.

Mine has the MBC model number and date stamped right there in front. If yours has an extra coat of paint, it might be obscuring this factory stamped info.
Try shining a light on that lower area and view at an angle as well. Maybe you can see it.
