It never cease to amaze me when someone ask of the particulars of a obscure weapon and the Very First reply states "I would not have this Guneapon except for a Wall Hanger? Actually Trocaola Arms Was and Still Is a Noteable Spanish Weapons Manufacturer of Firearms and from 1908-1938 had more than a few Gov't Contracts. Granted the Steel used during this period was not the best available in Spain to be had neither was it to be considered "Nothing More Than Iron"!
The condition of this particular weapon lends itself to a much more comprehensive look. Heat Treating to an acceptable degree would not be a very hard task to say in the least. As far as broken parts go one would be overwhelmed with the availabilty of S&W Police Positive and Model 10 Parts to be had if they knew where to look and had a reasonable degree of skills neccessary to fit these parts as needed for this Spainish Clone.
Aside from the decision with respect to the application of a New Finish I see this Old Spainard in Cal 32-20 Win. as a very good canidate for the Fun Gun To Shoot Award. Now those that can make the destinction without really owning the above mentiod firearm will surely disagree. What can and cannot be done to an existing firearm is only limited by the knowledge and skill of the person in possession of that firearm and his or her dedication to repair or the restoration of the weapon.
Well I must have hit a nerve, and that wasn’t my intention, but the truth of that matter is that during the period in question, many small shops in Spain were turning out questionable copies of Browning pocket pistols (both FN and Colt) as well as revolvers that were specifically intended to look like more famous U.S. makes. They would also apply markings in a way that could and did deceive buyers into thinking they were getting the real thing.
As for parts and heat-treating. Model 10 parts aren’t likely to work because the model 10 didn’t come about until 1957-58, and by that time S&W was using a new short action with different lockwork. The earlier .32 1905 hand ejector has a long action similar to the Spanish revolver in question, but parts did not interchange between them. I suppose you could try to alter S&W and Colt parts, but then you would be faced with the need to re-caseharden those parts that were originally case hardened.
You can’t do much in the way of heat-treating low-carbon steel or iron – which is the reason that parts in even quality guns of the 19th and earlier centuries were casehardened. But this process was never used on cylinders or barrels.
If you still want to go to the trouble and expense of doing (whatever) to it, I have no objection. If you are determine to continue in this direction I suggest that you go to
www.e-gunparts.com because I believe they have some parts for these Spanish revolvers, as well as parts for Colt & S&W revolvers made during the same period. Again I would point out that there is no guarantee that these parts will work in the revolver you have, or that they can be altered to do so. Once altered, they cannot be returned to the seller for refund or exchange.
My point was to explain that it probably wouldn’t be worth it, and the money involved might be better spent. I was also offering a warning to others that might own similar revolvers, and didn’t know the background.
All things considered, I stick to my comment that they’re best use would be as a wall-hanger or non-shooting collectable.
The owner refused to believe it wasn't a Smith & Wesson because it said so on the barrel...
