1950s Correct original washer pump jar question

[Cadman-iac]

I'm not a stickler for exact originality,  but when I have a choice, I'd like to make it original.
I have 6 of these washer pump bottles or jars, whichever they are called by. There are 3 that have the number "5651" on the bottom with what looks like the old "A" atlas symbol on them. Then the other 3 have "Duraglas" cast into the bottom.  Just one has the number "82895" on it as well. And all three have what might be a date code also.
  So here's my question, does anyone know which one might be the original one for the '56 Cadillac? If it doesn't matter,  I'll just use the best looking one, but if there's a correct choice, I'll use that one. My guess is it's the one marked with "5651" just because it begins with the number 56, but I honestly have no idea.

My thanks for any help you can offer.

Pictures in this order, #1-"5651" jar, #2-"Duraglas #82895" jar, and #3-"Duraglas" plain jar.

Picture #4 is of the two rebuilt pump units with jars and brackets, and the third jar with a matching bracket.

Hello Rick,

Nice pieces, do they also work for ‘52? Are you parting with the others?

Oscar,
The pump assemblies are not for sale, as I only have the two complete units. One for in my car and the other for a spare in case it's needed.
However I don't have any plans for the other jars and/or the brackets if you're interested in one. You can PM me if you prefer and we can discuss it.
