Well, there was a 100 in very nice shape (Thanks Steve) clean, good imprint, almost non-existent brassing, spectacular nib (just a bit scratchy, as expected)...
... And a 58 in a writer (not collector) quality... quite a lot of small scratches, seems to have been overpolished sometime before, lever was with minimal brassing, bladder like a stone, and it is the first time I see a clip with almost no plating and which has been polished to such an extreme that the CS imprint has almost completely dissapeared (I will need a replacement clip ... anyone has o spare clip??) Nib and feed badly misaligned, tines also. The jewell lost all of its black enamel (not on the underside), had scratches and could not be screwed completely back in, leaving a loose clip... well, a good subject to play with!
The picture shows on the left side (column) the original status and on the right side the "after".
Tips have been smoothed and polished (not grounded), both write now like any of the best ones I have ever tried... As I say, this hobby gives a lot of pleasure, specially now, when the learning curve speeds up and gives good results!!
Let me repeat the question... any of you have a spare 58 clip to sell, share, trade, offer...
