Your spelling of "Draught[s]man" might have misled you for that one. It's a little sad that Netflix's search returned no results for such a close spelling. I'm not sure why you didn't see Name of the Rose.
(although maybe from your example link you are in Australia and thus don't have access to Netflix DVD?)

I spose I'll have to find them at an old fashioned DVD store, eg. https://filmclub.com.au/
