I`m looking for quite some time for a restored safety pen & hope that it eventually ends up being a Bayard!
Maybe amateur35 has one on offer at some point. Unfortunately he never describes the nibs very well & the photos are not that good.
I think amateur25 has a safety in his recent listings. Go check. I've never had a clunker of a nib when buying from him. I am fairly certain he would give a more detailed description, if asked.
