Pinhole camera light leak or something else?

I recently made some modifications to a pinhole camera that has worked
well for two years.

My first set of prints from the updated camera came back from the lab
yesterday, and the top 1/3 of every photo is overexposed. The
overexposed area runs in a straight line across the top.

I noticed on the negatives that the overexposure continues BETWEEN
frames. I guess this could be caused by a light leak or a mishandling
of the film at the lab.

I just doubt the camera has a light leak because it has worked well
for two years.

Could I be overlooking any causes?

Sincerely,
DC

This could be due to film handling. It sounds like you have a roll
film camera fitted with a pinhole. If you have 120 film, it might be
the case that there was some light exposure when taking the film out
of the camera. That's just a guess.
