It's almost certainly Tennite, Eastman's brand name for their cellulosic. (I think the Packard stuff is a butyrate)

I've filled cracks with epoxy or glazing putty. I'd use an epoxy. The real issue is that the material is generally oxidized and degraded by now. Acrylic (poly acrylate) solvent may soften undegraded Tennite, but I doubt it will touch degraded stuff. I'd consider a backside mesh and/or joint pins for mechanical reinforcement.

Don't use anything just because it says it's "for plastic" as that covers a wide range of dissimilar materials.
