Date on drivers side of a 50s Mopar block

[BobT-47P15]

One time, a while back, I discovered this date    (50     5-26)   on the side of a 1950 Dodge engine sitting in my garage.  I had also seen a similar number

on the block of an early 1949 model Plymouth.    I am presuming it either indicates the date the engine was built or when it was placed

into a vehicle.    I know where the engine/ID number is at upper left.  Do not know what the 587  or the 119729-6 to the right mean.

Just putting this out to see what anybody knows about those numbers.       Thanks.        Bob.

Dates like that are usually the date that the block was cast.  I'm not sure what the other number is, but I would hazard a guess that it identifies the mold that was used for the casting.
