Hi Capt7310,
I have the gumball release button that you need. I also have other gumball related parts, award card and reel strips for it, if you have any need.
The #TS1007J gumball release button (reproduction) is $7.00 plus shipping.
See picture below.
Also, just a coincidence, I am just in the process of finishing a restoration on my Daval Reel "21"
trade stimulator. It looked about the same as yours just a few days ago. Thought that you might like to see it. picture below.
