Want To Buy: old Garmin bluechart cartridges

[Sailorman Ed]

Looking for the Garmin BlueChart Data Card (not the MicroDS card)
HXUS030R
US031R
US029US039R
MUS010R
MUS503L
This is for an old backup GPS so cheap is what I am looking for.

What do those numbers mean. Have a few I'd like to sell but they are packed away where it's not convenient to get them. If any of the numbers fit the ones that I have, might dig them out.

These are the Garmin #'s.
Looking for FL /Bahamas and western Carib.
