Stamp on channel balance

A handy person from North Port, Florida says:
I need to order channel balances but my stamps don't match your options. Mine are as listed:
28d usb
28c usb

Thank you,

Hey, Scott. I see you were looking at our S380-29. Is that the balance you need? If so, a stamp of 28D typically corresponds to our 2840 option while 28C corresponds to our 2830. You may want to weigh your window sash just to be sure, though.
