Matthias Lieberecht has started work on the 125 panel, as part off his Bae Panel project. More information can be found using the link below. If anyone can help him out with information, I'm sure he'd appreciate it.
I thought the other interesting comment from Matthias was that he has now stopped work on his HS748 panel, as there was no longer a need for it following a certain recent release with it's own superb panel!
