Having a brain fart. Can anyone help me out with this wall material that was around in the 30’s and 40’s? Super thin.
It could be homasote.

Well, Robert, It is up to you, take your pick, Upson Board, Beaver Board, Tentest Board, Masonite, or Homasote. Now that I look at it closer, it could be Masonite. We are not there to sample it. Good luck.

Tentest is an organic mulch board. Old that would have produced in 1978, asbestos was still used in some building products. With a few exceptions, principally manufactured from cross-contamination, 100% cellulose, non-Cementous, & wood-based fiberboard products that do not contain asbestos.

I concur. Masonite, is a type of hardboard, engineered wood, manufactured by steam-cooked and pressure-molding wood fiber panels, in a process ‘patented by William H. Mason.’

Thought it was interesting all the different names that are associated with Masonite. This is from the WIKI definition.
“Masonite is a type of hardboard, a kind of engineered wood, which is made of steam-cooked and pressure-molded wood fibers in a process patented by William H. Mason. It is also called Quartrboard , Isorel , hernit, karlit, torex, treetex, and pressboard.”
That’s why I choose “Masonite”. Direct yet ambiguous.

First thought, Masonite. Seems to be the majority opinion.
Seen that before when I was younger.
Early 20th-Century Building Materials: Fiberboard and Plywood (fs.fed.us)
Hardboard
Most historic hardboard was 1⁄8 to 5
⁄16 inch thick,
although two boards could be glued together to make a panel
that was more rigid. Masonite Corp. introduced its first
hardboard in the early 1930s. The Presdwood hardboard,
from 1⁄10 to 5
⁄16 inch thick, was used for interior finishes and as battens over other Masonite products. Panels could be
nailed or glued vertically or horizontally, then painted or
wallpapered. A more durable product known as Tempered
Presdwood was introduced in 1931. Often, it was screwed
to studs and its joints covered with decorative battens.
