Apologies for not spotting this issue earlier.

First make a backup of the original wallet.dat.

Then please try the following: copy wallet.dat from the node directory to the directory containing a zcashd build (from source), and run:

zcutil/bin/db_dump -r wallet.dat >wallet.dump
zcutil/bin/db_load wallet.new <wallet.dump
zcutil/bin/db_verify wallet.new

Let us know the output of each of these commands. If the recovery was successful, you will get a message BDB5105 Verification of wallet.new succeeded. In that case, move wallet.new to the old location of wallet.dat in the node directory, and restart the node with the -reindex flag.
