What kind of blade to use

Hey guys,

First of all a big hello to all the folks on the site. Thanks for providing the opportunity to take advantage of all the knowledge available here.
I hope I'm not :deadhorse: with this question.
I have a barbers razor, see attached pics, and I'm wondering what style of blade this one will use.
I'm a beginner with the whole shavette cartridge deal. I have two WB straights that I've been using for the past year, but would like something that can be taken on carry on with no blades, but pop a blade in where ever you get where you're going and you can have a half ways decent straight shave.
Thanks for any insight you might have.
