Vintage Rotring 600 Silver Fountain Pen with 18K Gold Nib

Description

Vintage Rotring Newton 600 Silver fountain with Gold 18k stamped nib in L size.  ( From my research, it's a French Nib which they don't make anymore.  It probably stand for 'larges', which means wide.  So probably a 'B' nib.?)
Come with oval plastic box, both box and pen close snugly like new.  The knurled grip on the tip of the lid piece can be turned to indicate current nib size on pen.
Pure Bauhaus, highly collectible.
Being in storage and moved over the last 15 years so the exterior paper box has long since been lost.  Some surface scratches on outer casing of the box from moving and stacking.
Shipping to Continental US and Canada, all US shipping via courier to US then USPS tracked package.
Any other location, please inquire about shipping before offering.
