Have you considered emailing the originators and estates of those instruments. Dave Smith, Oberhiem and the Fairlight guys are still around. Perhaps they have official promo shots they's send to you and let you publish ?
Hi guys. I managed to get what I needed. and thanks for the call out on reaching out to the pioneers of this great gear, and the common license thing from Wiki. Actually did not know that was an option! Had some success there, and some folks here also helped me get what I needed.
