I think your right on the Art Deco look to the engraving. That's the style that fits best as far as I can see. I didn't care for engraved guns at one time, but over the years I developed an appreciation for them. Had I been able to afford it, I would have liked to own this unique revolver.Don't know about the gun but the engraving has an Art Deco feel to it, which could have been done in 1920 - 1930's that just my opinion as being a jeweler for the last 35 years styles I have noticed styles have crossed over to gun design as well.
The seller told me he sold it locally for $5500. and as far as a "bad acid trip" What about this one?I do not care for it at all, but that is all subjective. It reminds me of what a mediocre engraver would do on a bad acid trip. I seem to be in the minority here but that is my opinion.
