Estate sale coming up. Bike and Tricycle ID help.

[Majdotkool]

The pics are horrible, but maybe I can get some help.
I have been trying to ID the yellow bike but still am not sure, Monark?
I am pretty sure the tricycle is a Colson, but what year?
I think I have the Tiger figured out.
I hope everyone had a Happy Thanksgiving!

Yellow bike looks like a Elgin to me

Thanks! That’s what I kept thinking, but the seat stay had me questioning it. Do you think late 30s/ early 40s?

Late 30's Earlt 40's they made 2 versions of that frame 1 with a straight seat tube and one with a curved tube

The seat stay had me questioning it.

It was the concurrent Westfield-built Sears Elgin bicycles, (usually chosen for the catalog pictures), that had the triangle-shaped seat post cluster. The yellow bike is Murray-built.
Not sure about the yellow forks?
