Very early m101

I have an M101, serial number 1673 made in 1951. It must have been stored inside a long time as it is really cherry with civil defense markings, white iwth blue trim and the original od under the peeling white paint. Anyone know if they started with serial number 1? Mine was made by Linn Coach and Truck Div.

I have a 1963 101 bed that someone in a rebuild depot put on a 101a2 frame. It is almost brandy new(looking).

Picture?????

1984 Fleetwood trailer in the background and 2004 cat. This is Florida so the blue tarp comes in handy.
