KLscribbler posted a topic in ParkerHi all, One thing I've been wondering about the Super 21 (the upgraded 21 with a proper hooded octanium nib and collector). Is the sac nipple in the Super 21's aerometric filling system vulnerable to the same sort of softening that sometimes occurs on 51s? I just wondered about this while refilling my Super 21 - this one has seen continuous usage for about 45 years now without problems. (Well, ok, maybe the tines have gotten a wee bit misaligned over the years... but apart from that... it's perfect.) So far, my thoughts about maintenance of this pen ran mostly in the "if it ain't broke..." vein, but having become more aware of the (thankfully small) number of issues that could affect 51s (sac nipple softening, breather tube corrosion...), I started to wonder whether Super 21s are vulnerable to the same problems, and whether I ought to have the internals of my pen checked, just for peace of mind. Then again, it ain't broke, and there's always a risk associated with opening up an old pen. I would have to get a professional pen repairer to do it for me, as I've never done any servicing of pens that required heat or shellac. I don't think I would be confident enough to use this pen as my first practice, considering its sentimental value. On a side note, is it necessary to remove the hood in order to correct slightly misaligned tines on a Super 21? Mine has always had misaligned tines since I got it from my father. I've always taken a "grin and bear with it" attitude to it, since the misalignment is small, I write with a very light hand and it doesn't bother me that much, and most of all - I was afraid of cracking the feed or the hood if I tried to exert pressure on the tines in any direction. Thanks & regards, CZM
