Strictly speaking this pen should not appear here as nowhere on it do the magic words Mabie Todd appear. However I suspect that you will be interested.
I have always maintained that Mabie Todd never made a button filler; perhaps I am still correct? Have a look:
The pen is clearly of good quality manufacture and I do like the section in the same marbled material as the rest of the pen. Also note the pressure bar, stamped "Swan". The Warranted nib, stamped USA is a poor wee thing really and a let-down. I have a lovely old Swan 1 nib which, if it fits may well go into this fascinating and really rather nice pen. Incidentally I have never seen a Swan clip like the one fitted to this pen. Apart from the nib there is no clue as to where this pen was made.
Awaiting comments with interest!
