I need to try and repair the top carving on this GB case. It seems to me it would be easier to repair the piece if I removed it from the case. It looks like hide glue was used to attach it. Heat would be the way to loosen the hide glue, but I'm afraid it might also loosen the veneer. I haven't really worked with hide glue (or veneer), other than to clean off bits from things that have already separated, so I don't know how much heat it would take to loosen this. I certainly don't want to make things worse. Any advice? On closer inspection, I not so sure it is veneer, at least not the ultra thin kind. It almost feels like it is 1/4 inch thick. Perhaps steam bent?
