Agree with mramer's assessment - I usually attend the June Gettysburg show, but a conflict with grouse season prohibits me from hitting the October show. This show had more tables, & more people, than any June show I've attended. The area to the left when you enter the show was open for the first time that I've ever noticed.
Another reason (besides the stir crazy explanation) it was a big show was the large amount of non CW material (predominately WWII). I've heard criticisms in the past of the non CW stuff creeping into the CW shows - I'm more interested in the CW stuff, but I'd rather see a table of WWII goods than an empty table. Lots & lots of Nazi stuff - maybe it's like Confederate relics - that government was in existence for a short period of time which makes items more scarce, so more desirable. Confederate gear is more desirable to Southerners, who (I'm convinced) are more interested in that war (despite the defeat) than Northerners. Almost all of the battles took place in the south. More hardships were suffered by southern civilians, and accounts of those times are still remembered by many. (I have a bucketful of civilian stories passed down to me.) These last four sentences wouldn't apply to collectors of Nazi relics here in the states, but I think there is an acknowledgement of military efficiency of the German forces, and appreciation of German technology and quality of its military goods. There also might be an attraction in collecting gear from an evil regime. (Do not think that I am not very much aware of the horrible war atrocities, inflicted on a scale never seen before or since, committed by the Germans.) I've never purchased a Nazi relic, but I was given a Nazi helmet by a friend, which I think is "cool" (although I wouldn't display it in my living room). Those of you who know much more than I do tell me why you think there is an attraction for Nazi relics.
