…. Unfortunaely, only the 2nd and 3rd IF were 85Khz , The ist IF tuned out to be the original, thus all of the heavy mods were about a second oscillator which he must have removed the Xtal or whatever, as there was no sign of a secondary osc circuit coil either.

I’d bet coffee and donuts it was like 90% of the mods I see:  he got half-way to what he was trying to do, discovered it still wasn’t going to be a Collins receiver or saw something new (“Ohhhh!  Shiny!”).  The mod was never finished and the radio went into the junk heap until a brave and noble soul (that would be you) rescued it.  May your attempts to breathe new life into the poor, abused thing, bear fruit.
