Would this be one with a time-expired wing box?

the photos say its VX305 which makes it a C-130K
construction number falls in the 1966-68 time frame in the H model
sequence.
C/n 4273 XV305 C130K C.3
thought the wingbox problem was in the A models and those fall in the
1954-57 time peroid.

I'm pretty certain that the wingbox problem was actually in the E models. That is one reason why the USAF has been downsizing its C-130E inventory and replacing them with J's.
