That doesn’t look like 1966 NE trim.

The windows don’t look like they’re from 1966 either.

When the previous owners updated the windows, they probably updated the trim.

Do a quick lead spot test to confirm.

That trim looks good. If it’s original 1966 trim, you’d have to get custom trim to fit as all mill work now is smaller/thinner.

Just what I’d do being a New Englander and feeling with a 1910 building and red cedar siding from the 50s.
