Chris Abernathy forwarded this from Vince Griesemer:

The 47200 series stock cars were rebuilt several times between
their original build date in 1913 and the rebuild in 1943. In prior
rebuilds, the drop floors and drop mechanisms were removed. The
1943 rebuild mainly involved rebuilding and reinforcing the underframe
since they had reached their 40 year limit...

Was there a 40-year limit in those days? I thought this limit was a much
more recent rule.
