Bit more involved that that with the guild system. They controlled who could have a shop and in certain places and times could go tear down a "non-guild approved facility". I would need to read the suit; but could it be that she was actually wanting to leverage more money from the shop and so wanting them to pay for the use of a known stamp?
For a fun little example of the how things could work read in "A History of Western Technology" MIT Press, about the difficulties a red metal turner in Nuremberg had with the guild when he kept inventing better metal lathes.
What does the bottom look like? How's the underside of the heel? Any numbers on the front of the foot under the horn? We know a lot of anvils were marked for Hardware stores to re-sell and I have my suspicions that this is one of them and would most likely be a Trenton, Hay Buden or Arm and Hammer. The elongate "gracile" configuration
Buckworth Hardware does show up in google (Sorry if this is all covered in the video can't watch it at work)
ok had a moment to dig and found Hedroit the blacksmith with his wife forging nails. 14th century AD: https://www.pinterest.com/pin/426364289699405293/ This is one of the pictures I remember. though I was using it for documentation of my medieval anvil...
I got a triphammer from an old farrier who used to make all his own shoes---he bought his nails though...When I originally tracked him down he wasn't interested in selling but I left my number and 3 days later he called and said "My wife has told me I've been kicked in the head for the last time and I'm retired, come and get the hammer!"
Where are you at? I once filled up a flat rate box with spikes for a 15 year old whose parents would let him forge but not scrounge---wise parents. I can generally find a gracious plenty of them at the scrapyard. You can also buy them new from the manufacturers.
Well most of my information is for Medieval and Renaissance times what era are you re-enacting? As I recall the guild laws in one place/time stated that Women could only work in the shop of their Father, Husband or Son. There are several paintings that show women forging due to the urban legend that a woman forged the nails for the crucifixion. None that I recall show them in appropriate forging garb... Women were also used in the small chain forging in England during the early industrial revolution. Also look for their participation in the Sheffield cutlery industry; though as polishers IIRC. (and you can always remind folks of Calamity Jane...)
So I had a quick trip to visit my wife and get her swamp cooler on our central NM house working last weekend. Not in my plans or schedule but more of a rescue mission. Anyway to sweeten the trip I stopped off at the Las Cruces Flea Market both on the way up Saturday morning and the way back Sunday morning. Saturday all I bought were a couple of Mangoes; Sunday I picked up 20 sanding disks for my large angle grinder and a pair of diamond farriers tongs is excellent condition---light in the hand, fairly short reins, convenient jaw opening and only US$5! Wouldn't even set them back down on the table to get my wallet out...(also picked up enough english muffins at 1/2 price that I can stuff my freezer and have breakfast covered for the next month...) Same fleamarket just a day apart; or to quote: "Constant Vigilance!" is needed to find stuff cheap! (I allot the time it takes to my entertainment budget...)
When I moved I was lucky enough to have a family friend with a 4wd "manipulator" who ran the pallets off the flatbed semi all over the desert and into the shop door. Once in the shop with the concrete floor I used rollers and a come along when necessary,
