Different along a timeline or different concurrently..?

The Tolley name had different iterations.
Holland this and that too.
Didn't the Purdey name go through a change or two?

Then there's the Brit gunbuilders with 'shadow' Belgian 'imposters' or out-of-towners seemingly having succeeded in riding the company name in more-or-less spurious fashion.
W.Richards etc anyone?

My old man (a native Californian) pissed fire the day Rigby came to California. He seemed to have known something (or two) that I didn't know that day.
Go figure.

Every day someone writes a new page in the book called 'History'...

Mauser?
Luger?

How about Colt..!?
