There were a lot of arts and crafts type things done in the depression of the '30's because it was cheap entertainment and oak firewood was not $2.00 a board foot.

One company that I know made church pews and had their master carvers making hand carved moldings for the office rather than put them out on the street.

You might want to have a skilled appraiser look at pictures, at least, before you start.
