Dating Redar hoses!

[boxerdogi]

Okay... that sounds a little creepy. I’m talking about manufacturing dates. It appears early hoses had the date stamped on the com. plate and nothing molded in the end. They then appear to have gone to ink stamping the com. plate and molding their name in the end. Lastly they stopped dating the com. plate and molding the date in the end. Does anyone have any thoughts or any ideas on when these changes took place?

Is that last pic a cute date calendar thing?  My eyes give me trouble, but I swear i can see a couple of the molded dots on it and possibly numbers at one end.

That last picture shows the Redar hose was made in the 2nd quarter of 1988.

You're right, this last REDAR hose end pic shows a 2-year manufacturing time span (88-89).

There are 2 molded dots out of the 4 squares in front of the year 88, and none in the 89 (so MFG. date was 2nd quarter 88).

REDAR is a generic term for all those hoses that comes from the R.E. DARling  company that made them originally.  Much like any copier is a Xerox machine, all hoses are called REDAR hoses no matter who made them.  Are all your hoses made by R.E. Darling?  If not, could different manufacturers mark them slightly different?

Yes they could. 
 

Here is one I have from the 3rd quarter 1970. Made by Oxytronics.

All of the hoses that I pictured are Darling hoses. I was really just wondering if anyone knew when they stopped stamping the date into the plate, and when they started molding the date into the rubber.
