"Any idea if my arm was original or remanufactured?"

Not definitively from my perspective. Perhaps someone who deals in Model A parts could look at your photo and determine whether it is an original or a repop. Repo arms looked like originals for many years and after 40 years on a Model A, who'd be able to tell the difference? I should think that even a marginal off-shore repo clutch release arm installed in 1980 would still be o.k., given that the last 40 years' use as a restored or unrestored driver car would have incurred far less use than one installed at the factory between 1928-31. I don't recall when I first saw the stronger repo arm (that looks nothing like the original arm) first became available, but it was surely a couple decades ago. That yours has cracked around the staking rivet falls right in line with how these arms have traditionally failed, making me believe yours is probably an original release arm. Should any readers' release arm break while on the road, clamp a vise grip pliers over the base to close up the crack. This should at least get the car home and save a tow truck expense.
