Close AM and Wide AM are varieties. Not in the Error category. 1990 should be Wide AM. It does not look like a close AM to me. There are no known Close AM for 1990.
THANKS ..so i posted another piece of worthless scrap? This is not a closed AM or a close AM before 1993?
Here is all the information you will need http://www.lincolncentresource.com/wideams.html It lists what to look for.
THANK YOU ..I'll go by this list for now on Thanks instead of wrong guessing and imagination my guessing is waay off the path.(Laffin)
Thank You for your concern. i need to use the guides instead of guess the varieties or errors ...also this site became addictive it is like gambling without losing money ...better... enjoy the site.
