Thanks for information - I was kidding about the caulk.. haha!!
For now, I put some tape down the seam till I find something to replace the gasket with or see other suggestions to resolve this issue.
It is a very thin gasket. I could not hear a leak, but could feel it on my face when I put it up near the seal between the two sections. I noticed it since it seemed that couldn't get out as many notes with a squeeze of the bellows as some of the videos.
The tape helped and seems to work more like I expect it to. Not having anything to compare it with other than just a "feel" for it.
I should have started this music project when I was younger and was living in Beaumont, TX.
In NE Texas at my Daughters, just not many cajuns in this area of Texas. At least there are the online radio stations to listen to.
