I'm not aware of any reliable method to date them, other than maybe 1940s or 50s? They show up on eBay fairly often (they're actually quite common, sold as surplus in the 50s/60s) and my recollection is that they mostly sold for around $100 or so.

Here's one that didn't get a bid at $165 earlier this month.
