Old Weidlich Pen

[Steve Kelley]

So my wife found an old "Weidlich pen, Cincinnati Ohio with "2 NIB". She wants me to restore it. Anyone know anything about Weidlich pens? It has an end cap like Sheaffer'slich do and then there is a little brass widget which presumably I need to pull out to fill the pen but it is stuck (of course). Should I attempt to remove the section at this point and try to diagnose how this thing is supposed to work and how I might be able to unstick the plunger?

I've never heard of Weidlich and don't know how to proceed safely. (I'll be in big trouble if I break her pem)

Thanks
