Window spring ballasts

A handy person from Rio Oso, Ca 95674 says:
Could you help with parts identify?

Top (black part)---- I read it as 19-002
Bottom ---- I could not find any exact please help.

Stamped reads 28 3 EK Caldwell.

I measured the metal channel and it measured 29 not 28.

Weight of window is 19 pounds but I have others with exactly the same numbers but with a 28 2 number.

Could you also give me approximate lead time?

Thanks,
Richard

Thanks for posting, Richard. Check out our 15-001 and 15-002 and tell me which is a better match to your hardware.
