Maker or marketeer?

Based on the education I've been getting here, the name on the barrel ain't necessarily who made it. Searching this forum only yields shotgun results. General 'net searches tend to lead here but otherwise didn't really tell me much.

I'd be interested in any information, particularly date of manufacture,

If pictures would help, let me know what and I will try to respond in a timely fashion.

Thank you,
Hoot
