Unusual Grieshaber

[D Armstrong]

We've got an interesting one on the bench. An early Grieshaber 5½", HR with gold-filled overlay. But not the hump-filler; this one has a barrel cut-out with a rotating protective gold-filled sleeve.

I've looked at the c.1914 catalog, searched the forums & web, etc., but can't find any references to this variant. Has anyone come across it before?

The pressure bar is loose, and just seems to be friction-fit between the sac & sleeve, rotating with it. Any thoughts on this? The last person to have a go at it seems to have put in an under-sized sac, and tried to glue the bar to the sac. Didn't work, as glue sticks oh-so-well to rubber. (Looked for the head-slapping emoticon and can't find it.)

Your observations and experience are appreciated.

A sleeve filler, that's so cool! Some early pens did have the pressure bar attached to the sack. It's certainly more elegant than the only sleeve filler currently on the market.
