This is an OMAS Olgiva AM87 in BriarwoodThis pen is in stunning excellent condition. When not in rotation it is flushed, dried and stored. The nib is an OMAS 18K two tone gold (stamped 750 on the nib) and while it is an "M" nib; medium I did have it tuned by a well known Nib Meister to achieve a fine line. It writes wet and beautifully.
