I have an early 1960's Pennsylvania State Police 870 Wingmaster. I ordered a Hogue overmolded stock and forend to lessen the LOP. The original wood forend seems permanently welded to the tube/action bar assembly. The lock nut came off with the correct tool, but I cannot get the tube out of the forend. Tapping, heat and twisting offer no help. Is there any way to get it off without ruining the wood forend, which I would like to keep? I expect decades of trunk storage warped/shrunk the wood so as to make it seem a permanent package. I don't want to fork out another $50 for an additional tube assembly. Thanks for any help.
