Hi all,  I did a bit or searching for more info on the elbows from
Grainger and this is it.  Yes, I did go the Graingers this morning
and picked up my order of brass elbows.  They are nice and shiny,
90 degrees, ID 1", OD 1-1/16".  The part number is 39R714.

Graingers may or may not have a bunch in stock.  They were in the
catalog for $8.59 each, but since I was ordering 15, I got them for
$7.47 each.  I'm sorry for the incorrect price originally listed in
my first submission.  They do work well and will replace those
crumbling lead elbows.

Best wishes,

Mike Walter
