I have recently contacted both Loyalist in Canada and Middlesex in NH. Both have zero guns or near zero and both told me the shipments from India are held up. As a general rule Loyalist will have some guns in stock (except now due to india and covid19) . Middlesex will never maintain a stock. What that means is some kind of deposit and you go on a wait list. The wait list is online with your name and position.
Middlesex is a guy running a business. It is not a family. I call the house several times and spoke to a very nice lady. Really a sweetheart of a lady. At some point I was directed to contact her husband on a new product. He does not speak, hearing issue, he writes. He wrote me the riot act about contacting his family regarding his business. Under no circumstances is anyone to call his home and disturb his family! Also refuse to discuss anything new in the works. He seems like an ok guy, but; a little rough around the edges and much sarcastic about certain pain in the neck customers. If you have a thin skin, go elsewhere. If you can accept his terms then all should be fine. I was directed to read the FAQ. Read it. It is funny if you dont take it personal. As a customer you better be able to read!!
There are some Italian and Spanish blunderbuss and kits. That is guns you can actually buy as opposed to getting on a list. I assume with steel that can be made hard all way through. As far as I know, much of the Indian steel is only surface hard. I do have an Model 1816 a real one, not a repro. It shoot sparks all day long. The old guns were a lot better than we give credit.
