Value of punch top

I have a vendo 185-A punch top coke machine. It is dated 1963,.My machine is not listed ,the185 is not an "A" that is listed,it was a bottle machine  I could not find any hole punching machines listed. was it just an option or did only certain models punch holes.Ihave owned this machine for many years and use it in my shop,I am quite fond of it ,and would like to document it ,and find out approx. value .

THANKS FOR YOUR TIME!
