ID For Three US Perfins Beginning With The Letter "D"

Can anyone assist me in identifying the user of these three US perfins?



The first one "D P" is on a Detroit, MI precancel from the 1926 regular issue.

The second one "D&M" is on an Auburn, NY precancel from the 1926 regular issue.

The third one "DLI" is on the Army & Navy For Defense Stamp and is not a precancel. Curious that it has two dot perfins at the bottom of the stamp, possibly identifying the location?

Thanks in advance for any help you can give in identifying these examples.

I believe that DLI is Dept of Labor & Industries, Bremerton, WA

The two dots are the beginning of the next perfin DLI
You are seeing the head of the "D"

Thanks for the help on the DLI perfin.

I had forgotten about this previous post, where the D&M perfin was identified as from a shoe company:

Now all I have left to identify is the "D P" perfin that is precanceled Detroit, Michigan. Any ideas? Detroit (Free) Press, maybe?

Is it "DP" or actually a freak "PD" (i.e., perfin is shifted way off center).

Then I would say, Parke-Davis.

I gotta get back into perfins, I'm missing out on too much fun.

Well, now I just googled it and came up with an earlier thread by... wt1!!

And in that thread is a Parke-Davis perfin!!

If you like perfins, join the Perfins Club. They are a warehouse of information. They also have a sales circuit with items priced from 10 cents each! All grades, all countries. {end advertisement} Ha!

I never even thought of that! I have these perfins in separate glassine envelopes waiting to ID and I have the "P D" one identified properly (in fact, I even suggested it in the previous post) it's just that I never connected the idea that "D P" could have been a freak that should have read "P D".

I guess I've now identified all three!

Thanks for the help.
