Yes, there were pictures. It was an interesting modification. The type of modification that was much more commonly done in the vintage era, than in modern days. Modern PADI divers would never do a modification that involved soldering and cutting metal.
The issue was that it had the big knob (the one found in some of the round label US Divers DH regulators), but this section is specifically for pre-1970 regulators. Therefore, based on the rules, round label double hose regulators do not belong here.
IMO, the original poster should just cover the the yoke with a piece of paper and re-submit new pictures, but that is just a personal opinion.
