Good morning.
George at Champlin's has a Lewis 20ga damascus that catches my eye. The specs all fit my needs but one thing is curious. The bores are .673 with .026 and .030 wall thicknesses. George has confirmed that the bores are indeed .673. The bores were supposedly opened before reproof in 2001. I have no reason to doubt his findings but it seems more likely that it would be a chamber sleeved 16ga. I'm across the country from Champlin's so I can't look it over 1st hand. Has anyone seen 20ga bores opened that far and still have decent wall thickness?

No....I think that you have it figured out correctly, likely started life as a 16 bore.

That is a very nice small bore, Bill. The long LOP with the nice leather covered pad is another plus. It's a beauty of a fairly priced Birmingham smallbore boxlock. Good luck getting an accurate answer to your question. BTW, wasn't G E Lewis more known for heavily built waterfowlers? https://www.champlinarms.com/Defaul...mp;mid=409&StyleID=10&GunID=3908
May God bless America and those who defend her.

Thanks for the note Stan. I have been eyeing it several mornings now.
Not sure about the waterfowler aspect.
I'm off to deer camp this morning!!

I have only had 1 deal with George at Champlin and it was 100% ok. Gun was as described, he sent it out quickly, the kind of dealer we wish they all were.
This ain't a dress rehearsal , Don't Let the Old Man IN

Might be worth a call to The Royal Armories at Keeds , I believe that they hold the company records.

This is for sure a Cyril adams gun. Guarantee it shoots like a dream. I have a number of them. He would often chamber sleeve unpopular(at the time) 16 bore guns to 20 and this provided more consistent shot patterns and less recoil as well. All of Cyril’s guns that I own handle like a dream

Looks like a Cyril Adams gun. I have a friend that bought a 28 gauge hammer gun that had been sleeved down from a 20 gauge.
Remember he once owned Atkin Grant & Lang so he had the right people working for him that could do anything possible.
My friend also owned one of his guns as well, a Robertson 20 bore that Cyril had sleeved out to 30" to shoot doves in South America with.

Correct about Cyril, I now own a 1907 Grant that he had sleeved back in 1994. I showed it to Atkin Grant & Lang at the Southern Side by Side and they were amazed at the sleeving job.
