Got aircraft hanger?

Hold on a moment

...You haven't been running these much recently, have you? Because they look a little dry, especially that last one. Always remember to properly clean and lubricate after they've been in storage for a while, and make sure no gunk has gotten caught up in them. The postwar models were built very well, and usually that's all it takes to get them working flawlessly again- 
never be ashamed of your O gauge, it's lots of fun! And it's rare to see them in such well cared for condition, too. I bet the naysayers are jealous.
