In the distant past, I used Peace Pipes some because they were all you could find for a small price, but they were prohibitively heavy, as well as overly restrictive, and when machined strap-on tongue mufflers started to appear, I put the Peace Pipes aside. 

John Tatone got started providing timers for FF, and then later, speed pans and radial engine mounts in the waning days of CL, and eventually wanted to retire, so he sold most of his business to someone else quite some years ago. 

A far better Tatone muffler model, the Calumet, was dropped by the new Tatone.  Anyway, AFAIK, the Peace Pipes from SIG are still the original design.  You really want something better than that, though! 

Tatone is one of the entities that currently belongs to Mecoa.  Check out www.mecoa.com for details.  Note that they list the peace pipe as 'in process'.  That probably means they'll make them eventually, but you never know. 

I had a peace pipe that came in a batch of junk off ebay.  I gave it the test fit to a couple different engines, and didn't like the way it mated with anything, or the quality in general, so I threw it back out on ebay and got rid of it.  It wasn't a very impressive piece as far as fit and finish, and it appeared to be NOS with no signs of ever being used.  It shouldn't be hard to find an alternative that would be a better deal, unless you specifically want the peace pipe.

Jim , to reply to your question I thought I'd try one on my Enya 35 [ 5224 ] but .....

After reading all the views from contributors I've decided to take your advice !!

Won't bother with a Peace Pipe .

Much obliged for all the advice guys , regards from an ex-pat Brit in the French 'sticks'.

There were three  Peace Pipe sizes. Eric got the idea of using one on the Fox .59 from seeing mine. I used the middle one and ground out all the baffles and made the walls very thin. Mine came out very light. I used the one I have on my Fox .59 swept Jet style stunt plane built in 1964. Then on three Fox .59 powered Vikings.I still have the jet and used the muffler last month on my AASr.
