Can anyone identify these custom Amiga 1000 ROMs ?

I found a set of custom ROMs in one of my spare A1000 motherboards. Has anyone seen something like this before and recognize the Part # ?

It looks like they are just 2 EPROMS programmed with copies of the A1000 Kickstart 1.1 ROMs.

I was thinking they were custom because it said Rev 11. I didn’t think stock ROMs would say Rev 11.

The only 'special' difference would be if they were either PAL or NTSC versions.

Kickstart v1.1 rev 31.34 (1985) is NTSC
Kickstart v1.1 rev 32.34 (1986) is PAL

Thanks for the feedback.
