Right. Done a lot more reading, and if I understand the various lists/pictures of Sheaffer models, I should be searching for Sheaffer Imperial IV (plastic cap, inlaid nib, touchdown filler). Going for the inlaid nib as another member said the conical nibs can be scratchy.

Thing is, there doesn't seem to be a lot of them out there. Currently one I am following on eBay is from a 'particular' seller and has 16 bids with 8 days left to run! It's not even a fancy nib.


So, are there any good reputable sources for this kind of Sheaffer that is not ebay?

TIA
