"Hand forged" is quite an open term. Most all blades are made by a human operator drawing the bar stock through the powered press by hand. They use dies in the press to get the fullers and overall shape correct. Then they are hand ground on grinding wheels to get the final shape.

Even before steam engines, water powered hammers were used for the vast majority of the heavy hitting.

The days of making sword blades with just two men and their hammers were long passed by the time this blade was made (and that includes the Napoleonic wars). If anything, the sheer number needed to supply an army necessicated more advanced production methods.

Looking at your sword, the blade profile is incorrect for the era of the Napoleonic wars, at this time fullers extended almost to the hilt and sabres tended to have more curve.

You can be confident that your blade is of 19th Century production. It has a later period scabbard with the single ring and if it's a good fit then they were made together.
