That one looks to be pretty clean and in good shape but the price still seems high to me. The National 13 pulls are big and bulky and do not have a good resale potential. Plus, it is hard to vend anything but cigarettes from those machines. I have seen those sell for $100 or less.
If you really want a cigarette machine, I would wait until an older National 9 pull or a 7 pull comes along. Those machines can be had for what this guy wants for the 13 pull, they are more marketable and have the nicer art-deco styling. The only problem with the 7's and 9's is that the coin bezels are usually cracked due to the coin return lever hitting the top on the rebound.
Check this expired E-Bay listing to see a 9 Pull. 130424872635 The 7 pull looks the same just smaller.
