Oh fine ..... blame it all on me!
And just BTW ..... I'm not a "55FREAK", but rather simply a Jensen #55 Aficionado!!! ;c)
But all kidding aside, I do believe you will find that extra barb to be of advantage from time to time.
Jan, that is a great use for some serious brass you have there!
Is the taller one an Anti-Aircraft Artillery shell?

Nice work Jan , does the job nicely.
Jan, if you decide to start selling these, please put me down for one!

Thanks Daniel!
I did "see the light", inspired by your past remarks.
Am certain they´ll come in handy, not just for twins, but also when running two engines side by side.
DANG! What if those two are 55s...need to make one with 4 barbs now

Thanks Ted, very flattering, but i won´t.
Anyway, if something similar is desired, it is much more fun and very easy to make it yourself
Nice Jan

Naw ... if you get that far into it, then either make another two holer, or use a couple of "Y" fittings .... but certainly glad you have finally "seen the light"! ;c)
Beautiful job soldering and cleaning them both.

Job well done Jan. Anybody can buy stuff, but when you can make it
yourself, it's a little sweater.
