Digital BW, The Print

Was wondering if there was a good Linhof online resource.  Would like to look for some more information about equipment in an old general catalog I have -specifically a 4x5 Polaroid back, ZTPB, (not the 405/550) for the linhof?

Did see the instruction booklet at craigscamera.com but would like to see if there's something on-line akin to the excellent Canon site.
Too many years of experience here to not ask even if a bit off topic.  At least I'm wanting to work towards some Type 55 with it!

Thanks,
Cleavis
