I want to buy a MB Ramses fountain pen but want to know if there are variations
of this model such as piston or converter fill and Limited Edition versus
Special Edition variants. Your opinions of this model would be appreciated also.

So far I have seen the Ramses in 145 and 146 sized FPs, a rollerball(legrand) and a ballpoint. I only have the 146 sized and it is an absolute dream pen. If I had to choose only one MB from my collection to keep, this would be it.
