Midland gun company

Hi, I know this post is old but I have a question or two regarding the Midland Shotguns.
Midland Sidelock-Ejector SxS Shotgun 20 GA
Serial# 92770, is there a way I can find out the history or date of it?

Thank you, and cheers to you guys from the USA.


Unfortunately, the ledgers had no rhyme or reason at Midland. Nigel Brown's 3rd volume says "1925-1954" for the age range of your serial number.

I believe if I had close up photos of the crossed halberd proof marks, I could decipher the exact year it went through the proof house. To get a clear photo, you might need to rub some white chalk on the crossed halberds. I needs to know the letters or numbers in the West, South, and East positions of the Halberds found on the water table or barrel flats.
 
The secret decoder ring for date of manufacture (or at least the date it went to proof) for Birmingham guns. Sadly, London didn't adopt the same precision until much more recently, but you're in luck with a Birmingham gun.

Hi, I have the Midland in my possession: I see BV, BP, and NP on the barrel. Please let me know if this means anything. And can you tell the chokes... Thank you!!

Happy New Year! Thank you for all that information, so was it redone in 92, or is that the original date, 1992? And to confirm, I should not put anything more than 20-gauge 7/8ths in this gun? I fired two shots on a pattern board, and they were on target 50/50.

Reworked in 92.

You should aim to shoot LESS than 7/8 ounce loads 3/4 or 13/16 oz. Always 2.5”, never 3”.

OK, that's tough, I do not load my own ammo. I assume I run the risk of safety on this with 7/8 or higher? Was planning on using for some fun skeet. I picked it up at an auction for $800 US... That's the risk of an auction site unseen...

You’ll probably blow your hand off shooing a modern shell in a short chambered, sleeved gun. Don’t do it.

Get rid of the gun if you can’t get 2.5” light loads.

Do you think if I get this ammo, it will be ok, or is there still a fair amount of risk? Thanks

Hi Dr. Ray, I will be in Cooktown from Oct 16 to Oct 23 fishing Lizard Island Black Marlin Tournament.

I have several "slack" days after fishing before I head for stay in Sydney and Fiji.

Do you have any recommendations for 1 or 2 day hunt near Cooktown?

I've hunted both DG and PG in 4 different countries in Africa.
Thank you,
Bob

Good morning. I see that you had a Sauer 202 for sale for $3,000. Did you sell it at that price?
I have one for sale as well. I listed it (on here ) at $3,000 as well. Is the price high, low or right where it should be?

Thanks. Alex. [redacted] in case you want to call me to discuss further. I appreciate your time help and support.

Dave, I could use both of them if still available. I just picked up a new .22 mag and a .22 pump that they would be perfect on.
