A wonderful high quality celluloid pen this by Soennecken, the Rheingold 1913.
A great, larger pen (13, 7 cms when closed) that has been restored with a new in sac fitted. The mechanism itself is renowned among pen collectors, being a unique twist on the button filler. To operate you unscrew the black hard rubber collar to reveal a white casein button which can then be clicked to press on the ink sac inside.
Nice clear ink window and generally in excellent order. Deep and crisp imprint of "Soennecken Rheingold" and the famous sunburst logo on the barrel. No signs of brassing to the pocket clip or cap rings.
Some browning of the hard rubber collar and cap top which can be polished back to black. Please note that, as so often happens, the small insert in the cap top has dropped out. I've done a quick fix insert of my own to mirror the insert.
The 1913 is fitted with its original Soennecken Pargo (Palladium Argentium) nib with a medium tip. This nib is so flexible that it actually feels like you are writing with spaghetti. The imprint states Soennecken Bonn Pargo. Nice deco lettering and design too.
So, a nice, rare pen that can be yours for $475 plus shipping.
