It's such a slow speed, low wing loading aircraft that it's probably fine (been flying for >15 years since last recovered) but I just want to be sure it's OK.
Am I thick?....or am I missing something?
OVER 15 years have elapsed, that means it had initial inspection and approval by a properly qualified person and, (unless it's a hangar queen) it has had at least 14 subsequent ANNUAL inspections by qualified persons.
I would think that any likelihood of it being of "dubious" airworthiness,has long been disproved.
If you're that anal, I'd suggest that "rag n' sticks" flying is not for you, consider a factory-built spam-can.
just get it flown....it'll add a bit of frission to the otherwise routine
