Beyond the fact that it is Dutch, I know nothing of the history of the Winstona. Searching online I found one other example. It was the same model of pen in a similar pattern, just black and white instead of wine and black. There are things about it the remind me of other pens, but only by accident. It is roughly the size and feel of the Parker Slimfold, slender but solid. The clip is Pelikan-like and at the top the clip becomes almost a cowl, a little reminiscent of some of the better 1950s Conway Stewarts. And, of course, the pattern is a little like the Parker Vac.
But of course this pen is very different from all those, being a piston filler. Removing the black blind cap reveals a turn-button which moves the piston. The barrel is partly transparent and has good clarity.
It’d be interesting to know what the original nib was but it has been replaced. The small Parker nib, from a Junior or late Victory, fits well and is a good writer as Parker nibs generally are.
I know of only a few Dutch pens. Like this Winstona, they resemble German pens and are equally well made. Quite how this one made the journey across the North Sea we will never know but I’m glad it did. I’m grateful for the opportunity to see this uncommon and attractive pen.

I agree Deborah, it’s an attractive pen and with all those transverse bands my first impression was its similarity with the ’30/’40sParker Vac. – assume the nib is a replacement – is it celluloid do you know?
There doesn’t seem to be any help in my few books – Dutch made pens don’t seem to get a look in, unfortunately. The script of the barrel imprint is attractive. We need a contributor from Holland.
I think the main body and cap are celluloid. The blind cap is made from plastic. I’m going to ask around and try to get more information about this attractive pen.
Theres a coincidence. I dont normally go to car boot sales, but I did last Sunday. Only one seller had any pens, a Platignum set and a plain black Winstona. the piston worked very well but the nib wa sa poor thing, XXF and a bent over jobbie. He wanted £10, I offered £5, not really wanting the pen to be honest. He counteroffered £6 but by that time I had lost what little interest I had and walked. Had the pen had the Vac like pattern then it would be a different ending.
Thanks for that, Robert. That’s three I know of now and it’s interesting to know there’s a black one. Was the nib gold? Mine has a replacement nib and I don’t know what the original was like.
Amazing coincidence. For that money I think I’d have been tempted to buy the boot sale pen – there are nib straightening kits – not that I have one – I tend to simply invert them in a channel and cautiously apply pressure from above. I doubt there are many nibs that can’t be improved to some extent …………… perhaps Deborah might give some tips on nib straightening:-)
I’ve ceased with the boot sales too – the results weren’t repaying the early mornings and cost of transport etc. I notice that for some reason there seems to be a recent lull come over the charity shop results, although this week was more of a red letter day, so it pays to persevere. Perhaps the holiday season has taken everyone’s mind off sorting their bric-a-brac.
I don’t know if there are any particular tips I could give. For years I used a boxwood pen rest and the polished back of a dental pick. Then I bought a proper kit – the rather splendid one that Laurence Oldfield sells which undoubtedly makes life easier. I also have a jeweller’s anvil which can be handy. For the rest – careful pressure, patience and a good loupe or magnifying headset. Sometimes you need to finish with an abrasive. The best advice I can give is not to begin with the idea that you’ll get quick results. Then you won’t get frustrated and make a mess of it.
