I've looked at all of the threads on these guns and haven't found an answer to my question - What characteristics are individual to the two different gunsmith's guns? Did the guns they built have exactly the same features or were there certain things that one did differently than the other? I'm wondering about being able to identify the origin of guns that are not obviously labeled as either a Jovino or Behlert.
This has been asked a few times and debated already but from what I remember...
There where ALOT of gunsmiths around the same time doing conversions. Some were high quality and some where not. Most that did conversions did pretty much the same thing i.e. cut and crown barrel, reinstall the front sights, action work and modify the SQ butt to round.
Not every converted N frame from that period is a Behlert or Jovino whether marked or not. There are alot of copies, some copies are even stamped with the gunsmiths name or model even though they were never touched by that smith. Also, not all Behlerts and Jovino's are marked which helps to confuse things for sure.
The rougher conversions had the barrels hacked off and either a rough crown or no crown at all. I have also seen conversions where the stampings on the barrel where never reworked and literally said "m and Wesson". I doubt either smith would have done that. I have also seen conversions where the front sight was super glued to the barrel after shortening and came off after solvent was used, so be careful.
In the end, what I looked for was whether or not it was a quality conversion and went from there, it did not matter to me who did it just that it was done and done well.
Below is a real deal Jovino EFFECTOR and a "who the hell knows who" high quality 25 conversion.
