Cool dress shoes! How old are they? "K" shoes?

Hey guys found these today and I'm amazed, so sleek and nice. The previous owner kept the upper leather in very nice condition. Fit nicely, sole needs work and the rubber on the heel is as hard as cement and it nearly crumbling off at this point. I think these are old... any idea what period? I couldn't find much about the brand online, the logo looks old and the leather on the inside is also aged and needs conditioning. What I have never seen before is that the serial number on the inside is hand written in black ink, I've only ever seen stamped numbers. The ink is faded and looks very old as well. The left shoe is creased a lot more than the right. Any idea what style shoe this is? I really think these are nice and for $10 can't go wrong IMO! Oh and also the inside of the toe box area is a very rich feeling suede and that is even in good condition.

Based on the style, those look to be from about the 1960s to me. I am not familiar with K Shoes specifically, but there were many custom shoe makers in Hong Kong around that era, and many of them had very similar logos. Perhaps they are in that category.
