Model A Shock ID

[DICK SPADARO]

Local garage sale some times come up with odd stuff. This one had these shocks out with some other old car parts. Now this by all visual is a Model A shock but for being so old it is in excellent condition, what I am trying to determine if this is actual an original part NOS or just an old reproduction that was never installed. Although it has a Ford script , it just says hydraulic shock and made in Chicago. I'm asking for some eagle eye Model A guys to set me in the correct path as to original part or old repro. I spent some time on the search section on shock absorbers and am leaning one way but want to hear from some sharp people on A parts. Thanks for your time when making a reply.
