Yes, absolutely. We want all valid serial numbers. I routinely include serial numbers found in Craig's list, eBay and other internet sources. Please be careful when reporting found serial numbers. It can often be difficult to read the serial number from a posted picture. Please don't guess, If you can't read all the digits, don't post it. This can cause problems with deciphering the date code or can duplicate a valid serial number.
