Leech also received the iron tubes and several iron canisters he had previously ordered from the blacksmiths.
The hollow iron tubes were made of two seamless layers, one sheathing the other, with the seams joined by forge welding. This level of craftsmanship was beyond what Black Ears could achieve.
It wasn't easy to produce these sturdy, straight, hollow iron tubes of uniform thickness. Following Leech's instructions, the blacksmith had also rifled the barrels and produced a batch of metal projectiles.
With that, the initial preparations for the firearm Leech envisioned were complete.
The next step was to go to the promontory caverns and have Betty try to create a firearm with these components.
Leech soon delivered the gun barrels to the promontory caverns. As soon as Betty received them, she immediately understood what he wanted.
