It is monochrome LCD I need to replace but there's nothing about the model number or manufacturer. It has flat 15 pin connector. Back light is separate supply with ccfl tube. I posted some pictures. The machine model is SAC-F4S.
The closest one I can find is this one: https://fsshijie.en.alibaba.com/product/60475361775-803277332/640x480_VGA_Monochrome_15_pin_9_4_inch_LCD_Display_LM64P839.html
But its over 100USD so I don't really want to risk that much in case it doesn't work.

Bit of a longshot but these might have a screen with a model number on or even a spare screen.. Is this the same interface unit? https://www.aesintl.com/equipment-services/manufacturer/elettromeccanica-carra/t1340b/

Here is the datasheet and pinout for the Sharp LM64P89 & LM64P839 panel:

The 3 power pins appear to be in the right place.

Thanks for that I will go and check the voltages before buying anything.
