If they were an actual manufacturing company I imagine only one or two reels of a model at best...
At the company I recently left (fine jewelry making) the founder (who's name and the company name are the same) would only make one or two prototypes of anything then these were turned over to model makers and R&D folks to make dies, molds, etc. to produce more that were identical or in some cases better due to small refinements. Although much of what the company makes has a high degree of actual hand work involved (rare in this trade today from a high volume maker) the work cannot be called "hand made" (due to laws from a national stamping act, etc.)...
BUT despite all that and that the company often talks about the "Design Team" in its advertising... Many MANY of the customers still think 1) All the designs are done by the owner 2) All the product is hand made...
3) That he still sits out under an oak tree making each item one at the time...
I don't pretend to know all about the historical side of manufacturing but if you consider the products made... My guess is from the mid to late 1800s any fairly large manufacturing company of widely used items were working in a similar way just in order to produce the numbers. Teams of craftsmen using the most sophisticated mass production tools of the day doing piece work production that was assembled by still more workers or craftsmen to match the original made by the designer.
But that is just my educated guess...
As to the sale-ability of a poorly made copy (which someone touched on earlier) there are large numbers of new and up-and-coming collectors or just folks that have heard that "old fishing tackle is worth something" that can't tell if all the parts on a reel are right but are still interested in a reel that seems to be a good buy or something collectible...
While I was at the recent Austin NFLCC show back in the start of the month one of the fake MOSCROPS "day and night" fisherman brass fly reels came into the auction off the street (you see them pop up on ebay too)... this was my first chance to handle one of the fakes which I was interested in seeing up close as I have one of the real reels... I was amazed at how poorly the fake was made, how badly it worked, how clunky it was in comparison to my reel. The quality of the art of the fisherman on the side was like the Pillsbury dough boy compared to Michelangelo's "David" in detail and execution... EASY to spot for the educated but due to the novelty of the reel ("Oh isn't this neat?") the fakes still sell! Most everyone at the auction DID seem to be aware that it was a fake, but it auctioned and sold anyway (though I think bidding was very light)... You would think to real reel collectors the item would be viewed as akin to so much Pier One brass bric-a-brac (no offense to anyone that works with Pier One intended...).
Ok I will get back to my drawing board now...
