Need M146 USA Number example

[NDT]

Need a hand from you guys, got a rebuilt 1961 Spencer Stafford Loadcraft M146 trailer and nowhere on it is the Army registration number. Carnac could not help me with the VIN backtrace. Does anyone that has a similar era trailer know what their USA number is? Might be 7E1234 format. I want to change the last digits somewhat and use it for my Former Military DMV registration. Thanks in advance!

What was the NSN and I can reverse search and get some examples. It might take me a week or 2...I just had my primary computer crap out and I am back on the one with the sticking buttons and no return key. Still it beats the new windows 8 or 10 or whatever on the spouses computer which I can't use without cursing every 5 seconds.

Thanks Carnac, PM sent. Grab you one of those ex-USMC Getac laptops from fleabay. My 4 year old has yet to destroy it like he did my Dell.
