Recently I was given a trumpet from my Grandmother after it was donated to the charity garage sale she runs each weekend. The trumpet is gold, with a lot of wear on the lacquer, and looks and smells old but that just could be the last owner's neglect to clean it. The logo etched into the trumpet above the bell reads 'JASON' in large lettering, and then 'Made in Germany" underneath. There was also a small code etched in the 2nd valve stating 'Z' with the numbers '2439' directly below it. Other than a strangely small sized bell and a different mouthpiece to most of the others I've seen, it seems very similar to a trumpet in all other aspects. Unfortunately that's all the info I know about it (Images below), Does anyone know who crafted this trumpet? (I did search the web for Jason brand trumpets with no luck)

Thanks for the pics! Do you think we could get a video or some recordings of how it sounds?
From the looks of it (I tried researching it too), it seems to me like it's an independent horn maker. There are a LOT of them, especially in Europe, and most of the old ones went out of business a long time ago because of increased demand and/or larger corporations bought the smaller independent businesses (like Conn-Selmer bought Benge when they were greatly dimishing). It also looks a little French, and maybe this horn maker refurbished it or made some modifications. Since we don't know, well, anything about this horn maker, the best guess I can make from the number of the horn "2439" is that it's an intermediate horn and maybe the production number 'the 2439th horn' (since it doesn't really indicate the size of the bell, bore, etc). From the mouthpiece perspective, it looks very French to me since it looks like the way Couesnon made their very first horns/mouthpieces.
Another good idea is to subscribe to TPIN (Trumpet Player's International Network). It's an email subscription list that puts you in touch with millions of other trumpet players. You can ask this question there and see what other say. I post there sometimes and I get very helpful and informative responses, even from current professionals!
