Not in any of their 70s "American Market" catalogs anyway.
In fact, at least in the American Market only the concert toms were smaller than 12", so your double-headed 10" tom could be:
1) A product of their Japanese market (of which I don't know much about),
2) Something "custom made" from a concert tom, or
3) A later version, as they did start offering them in the 80s. In fact, in the 80s they offered a small double-headed tom that used the "snare" lugs on it.
What's the shell composition of your 10"? That would help tell.
Hey, even though I take pride in my knowlegde of the 70s Pearl, if I'm wrong that's fine... I look at it as a "learning" opportunity, 'cause different sizes and other oddities do turn up from time to time...
