Any copy of "The Shooters Bible" from the late 40s to the mid 60s has a page detailing the bolt disassembly. Stoeger was the importer of those FINE, FINE rifles until they were discontinued. If you can't find a copy handy, let me know and I'll dig out an old copy and post the information.
Thanks for the suggestions! I have ordered a copy of the NRA Firearms assembly guide; I also found on a web-site instructions to disassemble the bolt, and I have already done so, and cleaned her up and reassembled. The rifle is indeed a jewel, and I look forward to taking her hunting this fall here in Pennsylvania.
