To my non-expert eyes, those look like commercial part numbers rather than unique to Lynx. Google suggests many of them are available from resto suppliers Macs, VanPelt, GreenSales etc. (you may want to try both with and without the hyphen, I took out the extra spaces when searching) BB-7228 seems to have a current NSN suggesting it has been used in something a lot newer than the Lynx.
