Thanks Dave.

After I posted that message it occurred to me that I have a second 110 NIB that I bought during the last production run. The regs are different! The newer reg has a bit of metal that should face forward as you mention, but my older one does not. The "blob" of metal that I referred to on my older one is in a different location. See the pic (this pic was meant to show you the crease and bubble in the regulator, but you can see the "blob" I was referring to on the left).

I also noted that the newer 110 has the 91-sized plunger in it! I guess they decided to switch back!? There is also a gasket on the newer one, but not the older.

Thanks again for your Sunday reply. I'm going flying now!

Kurt
