Ladies and gents, I've just come into possession of a couple of pens (one of which is a Sheaffer snorkel Clipper/Statesman missing its cap, if anyone has a source for those...) but the other is an English Waterman in BHR. Casting about the interweb seems to indicate it's usually known as a flat top and has no model number, or any great value.
This one has even less value, having a crack in the cap and a lot of plating MIA, but I've rather taken to it and would like to get it up and running as a user. However, at some point in its history, someone lost its pressure bar and I find myself in fresh territory. I gather it should be flat and hangs off the tabs on the lever bar (which appear to be all present and correct). So a couple of questions came to mind which extensive searching didn't really resolve:
a. Is it possible to acquire a replacement without too great a hassle? Unlikely, I suspect, but if you don't ask...
b. If not, is it possible to adapt a more readily available bar to fit? I'm not averse to a little drilling, filing, etc
c. Given that authenticity is not paramount, can I just fit a J-bar instead?
The last seems the easy(er) answer, but one comment I found suggested it puts extra pressure on the lever box (which is not, of course, designed for it), so maybe it's one of those Really Bad Ideas that us dabblers are prone to.
Hope the greater wisdom of the board can assist.
