Brass Part Identification

[Jess Mess]

Hello to all, I am including some pictures of fuel system parts of my 1948 build year, International TD6 and 1959 build year John Deere 435. In looking at the brass parts, they all have this logo/ hallmark of a “line inside of a diamond”.

Weatherhead had a “W inside a hexagon” if I remember correctly. Can anyone shed light on who this brass works and fitting company was. Thanks to the forum and responses ahead of time. Jess,

Imperial, later called Imperial Eastman

Thank you to Jim.ME,
So, I own an Imperial Eastman flaring tool and tubing bender from around 1978-82. Will have to go dig it out and see what we got for that era.

yep, Award First Prize to Jim.ME

Got the tool out of the catacombs and sure enough, there was that “Diamond Logo” on the Imperial Eastman tool.

Jim, If you are younger than me, kudos to you. I am in my eighth decade on this planet. I must say, you can still learn something everyday. I even looked on the internet numerous times and every search came up empty. It’s probably down at the library in some book listed in the Dewey Decimal System.
That’s what we learned in second grade, it’s different than the internet.should have started there first.
