WTB: Bronica EC-TL focusing screen w/ split-image

[Trask]

I've got an EC-TL with a microprism focusing spot, and I find I'd prefer a split-image focusing aid. I believe that such a screen is available, though I'm having a hard time confirming that to be true. If anyone can (A) confirm that such a thing is available, I'd appreciate it, or (B) actually have one to sell. EC-TL with the 15 LEDs, not the EC-TL II with many fewer LEDs.

Thanks!

Bump -- if only to get a reply telling me that a split image screen actually exists. At least then I'll know that I'm not chasing a mirage!

Bump -- I'm still in the market, for a screen or just information.

Bump -- ditto.
