Maybe it was surplus stock/components and there was one last client for a 32 bore hammergun?
When did Manufrance start making 32 ga and when did production end? Thus far have only seen 10,12,16, and 20.
Thank you Dave for knowing what I meant about "dolls head" I did not know the term.
MF was known for changing things up regularly, including their model designations. Without a specific catalogue listing from the year a specific gun is made, if the model designation is not on the gun, it's impossible to know what it was. Something that was designated model X one year could be designated model Y the following. Gauge is the same. In one year, out the next. Using catalogues from years other than the year of Mfc is just guessing. Educated perhaps but still just a guess.
And I know for a fact, having seen them, they also made 24 gauge, 28 gauge and 32 gauge. I do not specifically recall or have notes on seeing a .410.
