With restoration work it is always the unexpected that causing you the most grief. For six months of tapping, oiling, tapping, oiling, hitting, oiling, punishing; all done with hammers increasing in suitable size increments the locking pin on the 4.5 inch gun held firm.  To our great relief the pin eased gently out of position with the use of a large pipe rench and the threat of a cutting torch.  Bob's Garner's calming influence did much to keep the cutting torch at bay and helped bring this little saga to a close.
