One that she showed me, and with which I was very taken, was the Montblanc Model 145, Meisterstuck Classique, platinum coated version. This is slightly slimmer than the 146 and has a smaller nib. Also it is a cartridge-converter pen, rather than a piston filler. The platinum plated fittings looked really smart against the black resin.
Handling the pen, the body did not feel too slender for me. Uncapped, at around 122mm it was a bit short for me to use unposted but this is not an issue as it posts beautifully, cheap mont blanc bonheur Pen coming up to around 153mm, making for a very comfortable and balanced unit.

The tines were of course perfectly aligned. It was a joy to behold and all the indications were that it would write very smoothly and effortlessly. The nib was a medium.
