WELLER PIC firmware dump needed

[yabba235]

Hi !
I trying repair old soldering station Weller WD1 but I need fresh fw hex file for it.
This is first revision with PIC18F4620 processor.

Of course, I do not want it for free - I have to change the hex firmware dumps from models with the 18F6622 processor - WD1 and WD2M and dump fw from WD2 with PIC18F4620 CPU !!
I am also looking for the WD1 (M) or WD2 (M) schematic diagram - the second revision pcb with PIC18F6622 processor

BTW
All my dumps file is 100% good and working - I tested it myself
