Company types

For future reference, drawn from User:AvionHerbert:

Early aero companies have various suffixes to their names associated with legal classifications in different countries and we can define the terms here, their legal meanings, and any de facto observed attributes of the different types:

• G.m.b.H: German corporation -- “Gesellschaft mit beschränkter Haftung” – “company with limited liability”
• AG - “Aktiengesellshaft” - “private company”
• PLC (British)
• “Ltd.” British and American?
• “Inc.” (American)
• Societe -- French term
