hello Todd.
I am not familiar with this seller but no doubt one of our Canadian colleagues will be able to offer some information. However with just a cursory glance at the site I would say the prices are generally somewhat high.
About the NSKK ...I really wouldn`t give it another thought if i were you. The condition is quite poor & it is expensive for what it is.
here is a link if anyone else would like to contribute an opinion.
LinkYou would do well to wait & keep an eye for something being sold by another collector, here or on WAF forum; or alternatively try one of the reputable dealers that price reasonably.
Paul Hogle (lakesidetrader.com) would be a good place to start & there is help & information on what to look for on his site. There are many others with a good rep who can be found in the advertising page of this site.
Here hope this helps!
cheers
Vaughan
