I need to rush off to work but a few quick first impressions:
Size: woah a lot smaller than I thought it'd be, the shape is slightly different but the overall dimensions mirror my estie J. Length is fine could do with a bit more girth.
Condition of pen: pretty good overall for a pen almost 50 years old, but the ink window is pretty dim, know anyway I can clear it up a bit?
Nib: sweeeet. Seems to be a stubby B with a bit of an oblique cut. Flow is a bit too much for this cheap paper but I'll see how it fairs.
All in all pretty happy. I've loaded it up with Iroshizuku Fuyu-syogun and I'ma take it to work to see how it fairs :D
