As Jay mentioned - see the Becker forum and search for "strip" and you'll get 40 pages of threads, most of which have comments about stripping a Becker, that it was done and by whom.
That said, any good paint stripper from any small or big box hardware store will get the job done. I'd recommend perusing the threads to glean "tips" on how to do it. I see you're in Michigan. One of the tips is that the stripping environment needs to be warm (> 70 deg F) for the stripper compounds to work well. Heat lamps, greenhouses and/or enclosed porches may need to be used to get the job done in only 1 or 2 applications of the stripper.
Some other tips would be masking, stamps/etching preservations, etc. Newer Beckers have laser etched stamps/logos and need to be etched to be preserved post-stripping.
