Bath time for the Wing Sung 601A fountain pen.

It has been over a year since I bought my first Wing Sung 601, a clear demonstrator, in June 2018. I swiftly bought another in Lake Blue. They have both been inked ever since. My review of this inexpensive Chinese pen can be found here: Another look at the Wing Sung 601 fountain pen.

In December 2018 I added a pair of Wing Sung 601A pens, which looked similar on the outside, but had a totally different, large tubular nib unit, rather like a Sheaffer Triumph and with a large, cut ebonite feed. Again, these arrived in simple cardboard packaging and with a container of silicone grease. However there was one more welcome extra – a tubular plastic hexagonal wrench for the filling mechanism. This also fits the 601, making it very simple to remove and re-grease the plunger or diaphragm unit, on either version.

Credit is due to the informative Youtube reviews of these pens, in Pen Talk by Chrisrap52. I learned that there are different types of filling mechanism, although both are operated in the same way by unscrewing a blind cap and pressing on a sprung metal rod a few times, whilst holding the pen with the nib immersed in ink. I gather that the older versions of the 601 (first generation) have a soft rubber bladder inside. These can be identified by a metal conical finial on the cap. The second generation (which I am looking at today) have a hard rubber plunger inside and are identified by a plastic jewel finial in the cap.

As it was high time my 601A’s had a bath, I took the opportunity to try out the wrench and disassemble the pens for a clean. The nib section unscrews easily enough and there is a black rubber o-ring to help prevent leaks. The threads are quite fine and on reassembling, it helps to begin by turning gently in the wrong direction, to correctly align the threads.

The filling mechanism, accessed by removing the blind cap, is unscrewed with the wrench. One was quite stiff the first time. The unit is then withdrawn from the back of the barrel.

The Chinese instruction sheet supplied with the pen does not discuss removing the filling mechanism, (despite providing a wrench for this purpose) but recommends leaving the nib unit to soak in water for 12 hours if changing ink colour and then flushing it with running water until the water runs clear.

After removing the filling mechanism, I was a little worried that I could not see a spring anywhere and feared that I might have lost it. However there is no need to worry as it is hidden underneath the rubber plug. You can find it by separating the two plugs with your finger nail. Once screwed in place on the barrel, you can press the plunger rod and feel the resistance of the spring. It works very well and serves to fill the pen within a few presses. The first generation (diaphragm) needed more presses, maybe 10, not that this was any hardship.

According to the instructions, you immerse the nib in the ink, press the button and release, fairly quickly, within a second, and repeat about 5 – 6 times. On the last press, you keep the button pressed down while you withdraw the pen from the ink; let go of the button and then eject about 5 – 8 drops. Presumably this clears excess ink from the feed so that the pen does not leak or write too wet straight after filling.

The instructions also recommend keeping the pen filled, to guard against leaks from temperature or pressure changes.

The pen holds a whopping 2ml of ink which, combined with its fine nib, makes for long intervals between fills. The push on cap, makes a good seal and I have had no problems of hard starts or skips, even after months of infrequent use.

This is a very enjoyable pen to use and to tinker with. It is satisfying to be able to disassemble and clean the pen so easily, now with a wrench that is made for the job and to spread a little grease on the threads and plunger. I must admit though, that I still prefer the look of the 601 with its hooded nib to the 601A, even though in use, it is more difficult to see exactly where the nib point is. I also found that mine benefited from a little nib smoothing with micromesh, to turn it into a super smooth, wet fine. It is hard to beat one of these pens, for value for money.

  1. I’m always fascinated about how other people do this sort of thing. Great post! Thank you.

    I’m interested–being a bit picky about stains in converters and so on, I get a little paranoid about regular cleaning. Recently, I started using white vinegar to flush nibs and converters, followed by extensive flushing with clean water. It cleans very, very well. To date, it hasn’t hurt any of the plastic sections or feeds, but I wonder about long-term use. I can’t seem to find anything that really gives much information on the relative merits… the acid pH of the vinegar always leaves me a little worried when I use it. Any thoughts/experience?

    1. Thank you Paul. I have not tried using white vinegar to clean pens and so have no words of wisdom on this. I have used only tap water, or perhaps rarely some detergent such as Fairy Liquid. I know Laura recommends using Waterman Serenity Blue in a pen to clean it, a tip I picked up from her blog. I do not have an ultrasonic cleaner. I heard recently that hard water can lead to blocked feeds which is a worry now as London is a hard water area. A good reason to not have too many pens inked and standing idle for too long perhaps (which I am guilty of…currently 23 inked). Refilling a pen regularly from a bottle helps keep the feed channels open.

      1. Thanks! This is a thorny area, and needs more research I think. An ultrasonic cleaner has long been on my virtual shopping list… I might have to look at that more seriously–can’t help but think that the vinegar is risky, or we’d be reading about more people using the stuff 🙂
