Value of IO360-C/D plus props?

[Skymasterdriver]

My engines are Io360gs but I think that is just different accessory case and props are new style not the old screw in blade plus all the engine instruments. My 30k was a feeler to see what people think and can make offers. My old engines run so well I may overhaul them and put them on experimental projects I’m going to start soon. I popped some accessories off the others day, I can’t believe how beautiful all the gears are, these have been on since 89-90.
