I concur with last poster...the DACA shows seem to be the best place to look for milsurps and militaria of the DFW shows I have been to....
It was a great show for me...got a chance to meet Martin Ivie, who wrote THE book thus far on AK bayonets....I bought it several years ago, and helped me build quite a collection of AK bayos, including some fairly scarce variants...bought another copy, and he wrote a nice inscription and signed it for me. Had a nice long chat with him too, great guy.
Also was able to pick up a beautiful Rundblick Fernrohr fur FlaK for $100...these were the indirect laying optics that fit on top of the 88mm FlaK guns. A great addition to my German optics collection.
If I had more extra money right now, there were a few really good deals on milsurps there...and some really nice militaria...
I guess if you are strictly looking for stuff easily ordered online, gunshows may not be the best venues...but I still love the shows...
I will be set up at the next DACA show in November...can't wait!
