Hello, I'm new to the forum and new to collecting! I attempted to replace a non working growler in a Hermann Teddy bear I purchased recently. When I opened up the back seam, I couldn't see the growler, nor could I move the excelsior stuffing out of the way because of long threads crossed along the inner back. I also noticed there were Styrofoam bits in there. I am new to this, so I don't know what to expect but didn't know if this was all normal. Is it still possible to replace growler or will moving the inner threads disrupt the teddy bear?
