Looking for Mettler Scale ROM backup

[gmac34]

Hi, I have a Mettler scale with a bad ROM, I tried to contact Mettler to see if they would share the 30y old ROM file with me but did not get an answer. 
If anyone has a copy, I think I need the "STANDARD SOFTWARE ME-34172" any version between 10.45 and 10.50 should work fine regardless of the model of the scale, this should be compatible with all scales from the era with the same cartridge ROM system.

Attached a picture of the cartridge, inside there is just a regular UVPROM
Thanks!

Can you upload a ROM dump? Or perhaps several ROM dumps? Perhaps it would be possible to perform a bitwise AND against all your dumps to create a hybrid ROM, assuming that errors are intermittent.
