Hello, I've just returned from an early morning antique store run, and I bought some pens. There was a case of miscellaneous stuff in a corner, and I among the riff raff I found a nice little Waterman 52V and a slightly discolored but oh so smooth Parker ladies Duofold in green. I have some questions: What size sac would I use for these pens (necked or straight)? Should I get these restored by a professional or is this something I can do myself? I've resacced an Esterbrook and a couple of third tier pens before these. Sorry if this is in the wrong subforum, feel free to move it if necessary.
