You probably got it for a steal. There's one on Ebay for $390 that's nowhere near as nice. I've not seen one for less than $200.
After viewing the item at the antique store, my wife and I retired to a nearby pub that had Guinness on draft. Did an online search to see if the price was in the ballpark; it was. IIRC, the online $200 one was actually missing the ceramic ashtray. Stoked with stout and onion rings, we returned to the store and bought the ashtray. They had several other similar aircraft ashtrays, including an art deco one with a nearly nekkid woman, a Spitfire, a P-38, etc.
My main collectable target is "space kitsch," the kind of stuff sold in the '50s and '60s to capitalize on the space race. But I'm a sucker for aviation stuff, too, especially toys that show actual unusual aircraft. Got started with this tiny plastic toy of the Boulton-Paul Defiant...

The Defiant was the worst fighter of WWII...which led me down the rabbit hole of figuring WHY a company went through the effort of making a toy of it. A little digging online revealed the probable answer. The Defiant was introduced to much publicity in the spring of 1940, and in 1942, Britain's Acme Plastics issued a set of Battle of Britain fighters, including the Hurricane, Spitfire, and Defiant. I'm guessing that Acme Plastic's lead time to design, prototype, and make the models would have been about two years. So the Defiant was included from the beginning, and just carried along after the design work was completed.
An American company, Thomas Toy, picked up the little fighters after the war. I'm guessing there were few people in the company that knew the difference.
Anyway, this particular antique store was shy on space kitsch, but had one of the biggest selection of old aviation toys I've seen. Most of it was just generic airplanes, which aren't of interest. One exception was a tin toy of the Boeing B-50.

The B-50 was an interim bomber based on the B-29; I'm, again, surprised a company went through the effort to make a semi-accurate toy of it. Considering its similarity to a B-29, I'm also surprised that it was a Japanese company that made it. The toy is huge, about 19" wingspan.
