Thank you for your reply. Here are some other photos. I have not yet had the time to remove the truss rod. If there are uncertainty after these photos I will remove it.

i think it is from early 00s but I am not sure.
I found this on the Gibson webpage:
Les Paul Classic 1989-2014: This model features an ink stamped serial number with no "MADE IN USA" (just as we used on the original 1952-1960 Les Pauls). Most will be 5 to 6 digits in length, but the earliest examples feature 4 digit serial numbers. There should be a space after the 1st digit with the 4 and 5 digit serial numbers, and no space with the 6 digit numbers.
The 1st and 2nd indicate the year of manufacture for the 6 digit serial numbers which we've been using since 2000.
It should therefore be from 2005.
