Appreciate if you could elaborate...
You sent in a "full window" 146 for MB service and they returned it as a newer "striped window" 146 with your old nib swapped over?
Might I ask roughly when (year?) did they serve you & what level service it was?
Does this mean MB cannot fix the "full windows" anymore? No more parts?
Sadly my big window 146 has sprung a leak
Can't recall exactly when, as I've had a few services recently - but definitely within the last five years.
And all replacement parts are modern - so you would get a striped ink window.
I had had this pen for years, replaced a few broken collars and some other bits and pieces - but in the end a barrel crack (leaking) was the final straw which meant a service was necessary.
I did try to purchase a replacement barrel (ebay, classifieds etc) but never found one.
However, on a positive note, the pen I got back is a superb reliable daily writer.
It was a level two service and everything was replaced, except the nib and the cap.
(I had read that the older caps wouldn't fit the new bodies, but this one fits perfectly)
Sorry to hear your pen has a leak. I'm afraid that unless you can find a replacement barrel, you may have to move on to a striped window, via a MB service.
