Is your cousin’s name Nathan by chance? I just got an email about a similar story. If so, like I told him, until there’s a serial number, it could be hard to locate, and can still be hard to locate depending on what happened with/to it since 87. I hope you can find it, hopefully you can get a serial number and I have it listed! But also remember, it could have been sent to salvage, or turned into a puller, at that point, it may be gone for good?! But I’ll help out the best I can once we know the serial number!!
