Obsolete Norwalk key (Ilco 1018, Keil 128), how old is it?
Have a very old Norwalk mortise lock with pin tumbler cylinders that takes an unusual shaped key--it has two 90 degree bends in the middle--like an H with the opposite top and bottom legs removed. From what I can determine, this is equivalent to the Keil 128, Ilco 1018 blank, which are long obsolete. Does anyone have an approximate date when Norwalk was using this keyway?
Thanks,

That something new about using Medeco cylinder. Only thing was think about trying to find out of what he mean the cylinders are non-standard diameter— bigger than the standard cylinder but smaller than a master ring cylinder. I was think as he talking about Corbin cylinder but Pete gave information about it.....Timothy....

Pictures of lock and cylinders
Here is the mortise lock, cylinders, and closeup of the maker's imprint on the deadbolt. This is a double cylinder lock with no stop buttons on the edge, and a latch bolt that is not reversible. I've never seen one like this before now. The keyway looks like it would be double-sided, but I cannot be sure since I've never seen a cut key for this lock. Compared to the typical Norwalk locks I know about, this is truly an oddball.
