Colt OM vs OMT: What are the differences?

[slick6]

I was looking at a Colt .22 revolver with a last patent year of 1926? The barrel was marked as an Officer's Model(Instead of an Officer's Model Target)? To me, these guns look the same? What are the specific differences between these two target revolvers(Both with 6-inch barrels)?

In equivalent condition, do collectors value an OM or an OMT differently(Assuming that they are approximately the same vintage?)? Please clarify this?

I'm not an expert but I've never seen or heard of an Officers Model without the word Target or Match thrown in.

Pre-WWII there were three "issues" or versions of the Officer's Model.

These pre-war models were "officially" named as the Officer's Model Target, but were usually MARKED as the Officer's Model.
It's likely there were variations of barrel markings over these pre-war years with "Target" being stamped on the barrel or not.

The First issue was made from 1904 to 1908, and was totally different from later guns. These had the side plate on the RIGHT side of the frame, and the cylinder rotated counter-clockwise.
This early version was a target version of the Colt New Navy.

The Second Issue was made from 1908 to 1926.
This is the more familiar Colt Mid-frame with the side plate on the LEFT side and the cylinder rotating clockwise.
This is the target version of the Army Special/Official Police.

The Third Issue was made from 1927 to 1949 and other than having a heavier barrel, is essentially the same gun as the Second Issue.

My only experience with pre-war OMs is a 1930 example I own and it's marked OMT on the barrel.

Mine is marked "Officers Model Target" on the barrel.
