I was fortunate to fly the 180 and the 185 in the early 60's.
I have never been able to decide which I preferred. The 180 was more ' de luxe" with the interior and the 185a was more of a utility a/c. When empty the 185 was a great performer all round and was a great load carrier to boot.
We ( Flinders Island Airlines) used to carry up to 1200 lb of newspapers in the 185 and from memory was the only lighty at that time that would carry its own weight in payload.
They were so superior to any other lighty that they were in a class of their own!!
