GM nostr. Here’s a picture of some brick. This is an American bond common 1880-1910. Notice the six stringer courses for every header course.

I assume those header courses are full bricks facing inwards? How does the inside of the wall look? Maybe they are 2 bricks deep?
Inside in flush and stuccoed. But yes the wall is at least two, but probably three course thick.
