Copo BE Rear

[1969BaldwinCopoMotion]

Can anyone tell me if there’s a common date or dates for the rear axle code on a March dated 69’ BE....I believe they were made in batches on the BE Copo 4:10
Thanks,

My 03D COPO is BE 0317

Never heard of another one dated like that and there are other 03D cars out there.

There are at least 7 March BE dates.
