Alas, I'm not so pleased with what I see here with back #3. Roll #4, frames 2 through 12, plus the trailing end, all had
the bar seen here. Seems a foam light seal in the back is reverting to plastic goop. Since the back works well otherwise,
and I paid half the usual going rate, I shall replace the seals as a little project (it's not too bad a job to do).
