I have an original 15" metal globe body. One side of the body is fine, and a lens easily fits into it. The other side has been slightly tweaked, and a lens doesn't quite fit. I put a tape measure on it and the diameter on the tweaked side varies from about 14-3/4" to 15-1/4". Any thoughts on how to get this back so that it can safely hold a lens?
Thanks in advance ... Dan
