Born in 1915 and then enduring the "great" depression, my father was as thrifty as they come, and extremely careful with his hard-earned posessions. In fact, he engraved his last name and Oregon Driver's Licence # onto just about everything worth more than a couple bucks. When he passed away, I inherited a lot of sound gear, tools, instruments, appliances, artwork, etc. Trust me, nothing spiffs up a 1950's German 35mm SLR quite like my dad's ODL scratched onto the nameplate right above "Contaflex." Today I went to donate a typewriter and some other stuff to charity and realized his last name and ODL were engraved on half the items. So I held off and came back here to see who can tell me what might be the downside to letting that info out there. Pop is long gone, but Mom still has his unique last name. Also, I now live at the address where he had that license (for decades). Here's my question - if I fail to obscure that info and it ends up in the hands of a meth head oxygen bandit, are there potential negative consequences to consider? Another negative I acknowledge is that I'd feel funny receiving something in an otherwise fair sale/trade with somebody else's ID obliterated, even if the serial number was still okay. What should I consider as I go to sell/trade/donate some of these things?
