Roy's book shows 3rd change's starting at 146899. I don't know exactly when they stopped offering 6 1/2" barrels. And, I don't know when 150057 was really shipped; ie, where did the 1911 date come from?

Here is what I do know. All these are 6 1/2", except the Pope gun, for which I don't know the original barrel length.

150026 shipped 8/29/1910 to Schwabacher in Seattle. I had owned this gun.

150057 shipped ?? - your gun.

150938 shipped 5/3/1910 to J A Baker. I had owned this gun.

Wonder if the 150000 to 151000 was a group of these 6 1/2" gun? Don't know.

I own 0135, shipped 3/23/1910 to Doug Wesson. A pair of these were made together, and 0136 went to Col Stibbs at the Springfield Armory.

I used to own 159654, which was an 8" gun shipped to Harry Pope 6/20/1911.

I used to own 170061, shipped 6/20/1911 to Scoverling Dale & Gale.

Just a tad earlier in serial number, I own 145875 shipped 12/8/1909 to W Bouyton. This was a special order featuring Lyman Ivory front and rear sights, and ivory grips.
