SK2 .TWL file format

[MB54]

I've had an SK2 for several years now and have loaded Jim's '54 C3 tonewheel sets JA54B1 and JA54B2. I have several sets of calibration data for the actual hammond tonewheel organs I'd like to try. The custom tonewheels take Level, Low Pass, High Pass and Resonance parameters for each of the 96 tonewheels. That's a lot of data to enter by hand 1 parameter at a time if I want to try multiple sets. It would be much easier to generate a data file, like JA54B1 and JA54B2, on my computer and then load it into the SK2 via the USB port. To do that I need to know the data file format. These files have a .TWL extension and I assume it is a Hammond file format specific to the SK organs. (SK1/SK2 may be different than SKX.) Does anyone know anything about this file format? I sent an email to Hammond asking about the format but haven't received a response. I can't believe it's proprietary code since it's just a data file, though they may be sensitive about any handshaking.
