Looking for MAN-10A 7 segment LED display

One segment of the display on my early model Fluke 3000A DVM stopped functioning yesterday, so I am looking for a replacement. Has anyone on the group got an old Monsanto MAN-10A display, the ones with the LED arrays visible, not the later ones with the 'light pipe' over the LEDs? I would be interested in one [or more] display, a Fluke 3000A display assembly or even an old, non- working Fluke 3000A for parts. Also would appreciate pointers to other groups that might be able to help. I tried Google and eBay without any luck.

Mouser lists this as a replacement:

I believe that the MAN-1 is a pin-compatible predecessor to the MAN-10A. Check out the auction for the MAN-1A on eBay:

There is another auction for a single MAN-1, but it has a higher starting bid.

Yes, I saw both of those, but I think the MAN-1 is significantly dimmer than the MAN-10A. Still, it is an option to get it running again.

Vague data from an unreliable memory. As I remember it, General Instrument took over Monsanto's Opto stuff (and it's gone to become sombody else since then), and they went to 4 digit numbers when other colors became available, so there may be compatible displays under a new number.

My suggestion is to find the website for the major Opto manufacturers and see if they have a cross reference guides for their displays.

dig, dig, dig. Found a 1986 GI Opto databook.

Looks like a MAN72A or MAN3x20A (where x is 4, 6, 8 or 9 for Green, Orange, Yellow, or high effiency Red) might be a sub if you can deal with the thicker package. These are .3 inch instead of .27 inch digits, with a .2 inch thick package instead of the MAN1A's .12 inch. The MAN72,etc. had no connect on pin 9 while the MAN1 uses it as an common anode in addition to pins 3 and 14.
