I have been offered to purchase this set of parts for $2200, but seems there are parts missing like shaft bearings and so on.

When I compare the photos of the bell 47 for the high hp project you showed us Paul, I think I will stay focused on the Ford parts which will be more than enough For my 200 HP project.

Any comments on the part set I have been offered?

If someone is interested, I can pass on the contact person located in the US

Lots of parts missing. Rumour has it a serviceable Bell 47 gear box is worth
$30,000 US. The Bell engineers claimed it was good for 1000 HP if the input RPM was 6000.

You may want to investigate that Russian radial engine reduction unit, it has a CS prop
geared accy case as well. Not that it can take (all?) the power, but I recall they were rated at least 200 hp.
