Apart from sales stock I have thirty or forty pens of my own. Mostly they are chosen purely for their writing capability.
This one is a Swan 1060, not the wartime one but the post-war torpedo-shaped pen. It is unsaleable because of a hairline cap lip crack. That could be repaired but the chemicals involved are dangerous to someone with a breathing problem. As my husband is so afflicted I no longer carry out that repair.
This pen qualified as a keeper on two counts: it is a Leverless, a filling system I admire and the nib is a very pleasant fine. It is semiflexible and the line variation is very easily invoked. I don’t usually care about flex but it can be nice for some things – addressing an envelope, for instance.
The pen was made in the late forties, a year or two older than the aforesaid husband. He says he wishes he had worn so well. He could live with a lip crack if the rest of him looked so good!

For me personally, the 1060 (with or without the number stamped on the barrel) represents the ideal fountain pen: eternal (with lowercase “e”) style (easily outclasses any expensive pen on sale today), light as a feather even if used posted, a barrel with a diameter that suits my bear paws like a glove, and fitted with a Swan nib (need I say more – no). I have amassed six of them, each with a different nib, and never get tired of writing with them. Their only weak point (and I realise you disagree) is the capacity of the leverless filling system. Perhaps I am too careful in twisting the knob but I rarely succeed in squeezing two A5 pages out of a pen fill (the flat top with the earlier system ingests perhaps a few more drops of ink than the later pressure bar). Thank you again Deb for writing about those pens, they bring me writing pleasure on an almost daily basis.
Hello again Hans,
Even I have to admit that Leverlesses are variable. Some take a better draught of ink that others and in repair it helps to get the right size of sac to fit the barrel. Too small doesn’t work at all and too large lacks the elasticity to make a good vacuum. The other weak point with the Leverless is flushing – it takes a lot of work to completely clean one.
I have been looking for a #4 nib for mine for a while. Originally I was told it took a #6 but that was far too big. Then I was told it took a #2. I have a #2 and it does fit but all the others I see have a #4. So, I am still seeking one.
On a side note, I assume you are talking about the chemicals used to solvent weld cracks. I have access to MEK here and have done several solvent welds with it with good success. Even two Pelikans that were snapped in half. I would be happy to help.
Because of bombing and the limitations placed on them by the government, the 1060 during and after the war might come out with any nib: 2, 3 or 4. Email me at goodwriters@btinternet.com and I’ll see if I can find a nib for you.
