Magazine identification and value?

[mholmes1]

I have 3 magazines that I acquired. All 3 have aluminum followers. One is defective (that is how i received it and have not broken it down). The defective one has S/N 2531, script "m", and what looks to be an "83" code. The second one has a script "e", a cross, and "63" code. The third has nothing on the base, but has the code "fxo" and "37" and "P.08" on the side near the base.

I'm looking to find out more about each magazine, and the approximate value of each, as I am looking to sell in the near future.
