The information I gathered over the years suggested this car was built in December 1948 (as a 1949 model year car) and shipped to the distributor in Washington DC. It was used by members of the Truman Inaugural Committee but was not an actual parade car. It was built to the aborted Custom Virginian trim package. The car was acquired by Ronco Motors in Bangor PA. It could be possible to have been re-tagged as a 1950 model year car if it was still in dealer hands as unsold and untitled on November 4, 1949.
VERY IMPORTANT QUESTION Where did the posted info come from? It appears to be a mix from the door post serial number tag, part of the top line from the firewall body tag and
?. The SPEC-FO number on the lower line of the Body Tag along with the ITEM and SCHED numbers are needed. A picture of the firewall tag would be best. A 1952 Kaiser Manhattan that surfaced in England had a similar situation and it turned out that someone had combined information from several sources and the new owner didn't know about this.
If you are a member of the KFOCI you should have received the KFOCI HANDBOOK information on CD (Version 5.0 is the current version. You may want to look at the items concerning reading body and door post serial number tags.
