Can anyone tell me what x-references to Dunham #1 and #1E traps? Maybe Mcdonnel or B&G?

Is the 1E the newer version of the #1? Both seemend identical and would interchange, but the #1 had a larger diameter disc in the middle.
Thanks, TimJust a guy running some pipes.0 -
Yes it is
the #1 has gone thru versions 1A thru 1E I believe.
If you have a bunch of #1 thru 1E traps you can get replacement innards from MEPCO (which absorbed Dunham), Tunstall or Barnes & Jones.

I have a mepco dealer right here in town and will try them first. BTW, where does a midget trap fall into the evolution of the trap?

\"Midget trap\"?
That's a new one on me. How about a pic? Do you know who made it?

Never seen one
doesn't appear in the 1922 Dunham Handbook- are there any numbers on the body?

last pat date is 1911. not a mark on the body. I have a few of these I saved from the trash can. Stamped on the brass of the cap just under the word Iowa is either B377 or R377...that is the only mark.

B&J doesn't, unless it's listed as something else.
