Waltesefalcon;
Yeah, maybe so on the refinish. Looking at the markings on top of the barrel I can see your point. Those markings on the side are awfully crisp though. Do you think that the top roll mark is the result of a weak strike? If it is a reblue then it's an old reblue for it has a dab of blue wear and a soft pleasing patina. It is curious how the refinisher would have "gotten a little too happy" with his polishing wheel on portions of the roll markings and yet left others so crisp and sharp. Your photographs would seem to show a bit of brushed surface finishes and I'm guessing that's not original. Could be where someone wiped it a bit enthusiastically with some rough or dirty cloth.
This is only a guess, but I'm wondering if
those stocks did not originally come on
that revolver. Those stocks were on a revolver used to hammer something with its butt. It is telling that your revolver's grip frame butt shows no corresponding marring of its steel surfaces. I've inspected other revolvers over the years that had been used as hammers and if the wood bore evidence of it then so did the metal. At any rate I love ... love ... love the styling of those target Colt stocks of that time period and those are correct style.
There are some other Officers Models First Issues scattered within this Google Images search for them. Of course other later models are also included in the page.

Sam Lisker's site doesn't have many Colt revolvers of that era pictured and no Officers Models. Here's one about a decade older than yours. It's the standard model and not a target model but blue finish and markings would be similar.

I've prepared and fired a goodly amount of hand loaded .38 Long Colt ammunition over the years for this Colt Model 1901, a U. S. military contract version of the Colt New Army, my first ever Colt revolver and owned since the late 1970s.
The .38 Long Colt is dimensionally similar the .38 Special excepting for length. Colt .38 Long Colt chambers are bored through with no shoulders so it is possible to use the longer .38 Special cases for the loads as long as the bullets don't exceed .38 Long Colt maximum overall cartridge length. For that matter it is conceivable that .357 Magnum cases could fit though I can't imagine any factory .357 Magnum cartridge that would be short enough to chamber in the .38 Long Colt cylinder without the bullet's nose protruding from the front of the cylinder. Of course that condition would tie up the revolver, rendering the cylinder unable to close. Assuming one persisted in chambering some .357 Magnum cartridge, perhaps with a short light bullet, into a .38 Long Colt revolver and attempted to fire it then he will have created a pretty fair imitation of a grenade. A heavy .38 Special load such as a factory +P load or a hot hand load would like grenade the .38 Long Colt revolver as well. A standard velocity .38 Special cartridge that would chamber completely within the .38 Long Colt cylinder probably wouldn't do the revolver any good, making it loosen up at best or, at worst scattering bits of revolver to the four winds.

I have used up to 4.0 grains of Unique in .38 Long Colt cartridge cases under 148 grain to 158 grain bullets. Didn't find it particularly satisfying as Unique burns "dirty" with much smoke and with residue remaining in the bore. Velocities are erratic, given to large extreme spreads. It seems to me that Unique burns cleaner and gives more consistent velocities at moderate to heavy charge weights. I'm unwilling to use moderate to heavy charge weights of Unique or any other powder in the old wheezer Colts of that era.
Being an old geezer, Unique is my very favorite handgun powder of all. I like quite a few others, but its ... well ... unique.
Early on I assumed much and attempted to make up .38 Long Colt ammunition by using standard .358" diameter lead bullets designed for the .38 Special. Took them to the range and fired them at 15 yards, only to obtain 12-inch "groups." Some keyholed.
"Slugged" the bore in order to obtain bore diameter measurements and found that my .38 Long Colt revolver's bore was .362" in diameter. An expedient switch to the .38 Special 148 grain hollow base wadcutter gave perfect satisfaction. The hollow base of the .358" diameter target bullet will obturate well enough to fit the .362 bore and give quite good accuracy. The same 2.8 grain charge of Bulls-Eye with which I enjoy loading .38 Special target ammunition when using the 148 grain HBWC gives great performance with this same bullet in the .38 Long Colt. Velocities are in the very low 700 fps range.
It is said that the .38 revolvers Colt produced after 1903 all came with .357" diameter bores.
I confess to occasionally just using the untrimmed .38 Special case with the Bulls-Eye target load and the 148 grain HBWC in the .38 Long Colt. Not really authentic but the flush-seated wadcutter ammunition in .38 Special cases chambers with ample clearance in the .38 Long Colt chambers.
