Ok, this can get rather involved, First I would get in contact with Clyde Smith, Jr. ( www.cubdoctor.com ) supply him with your serial number (from the data plate ) He will write a nice report from the factory notes that he has. This report will include serial number, Fuse Number (which is different than the Serial number) Original registration number, options, Mfg date and roll out date. There is also some other neat info. It is just one page but there is some vital info for $18.00
Then, If it was Ex-Military get your Aircraft card from Maxwell AFB, turn it over to someone like Jim Gray (email@example.com) Pres of the Sentinel Club to interpret. It'll cost but, well worth it.
As far as the Civilian records, that is just a case of getting the Feds to dig through their archives...
Hope that helps,
