Or perhaps I should say just one of many Mabie Todd mysteries!

For the first time in a long while I happened to have a Swan Leverless L212/60 and a Leverless 0160 at the same time.

The top one is the 0160 and yes, you’re right – they’re identical. The parts are interchangeable.

Why did Mabie Todd have two pens the same with different model numbers? My guess is that the L212 pen was very popular and when they changed the numbering system they kept the model but gave it a new number in line with the rest of the range.

Whichever of these pens you have it’s one of the Swan greats.
