Hi Michael
May i say no ... at least semantically?
Technicalities apart, and giving place to connotations, this would belong to the class of "pepper boxes" (poivriers, pimenteiros), only later appearing those labelled as "revolvers" ... having had an intermediary hybrid, so called "transitional".
Could it be that, the early term for multi shooters was connected to the "repetition" terminology?
BTW, this French Apache setup was more an impressive resource than an efective weapon ... says i, in my innocence
