Here is an amazing extremely rare pen, a large Siebert & Löwen MATADOR TURBO in Lapis blue celluloid!!! These were the original prewar MATADOR pens from Siebert & Löwen. This legendary company in Wuppertal dated back to 1895! 

 One of the flagship models back in the day inspired by the new motorsport racing rage back then.  I have never seen such a large size Turbo before and this one has some gorgeous patina as well, adds such character! This has a #5 nib ( like a MB 146 nib ) and what is amazing is the nib is made in New York for Matador! This is quite the nib, large, well made with wish such a lovey XF point and springy flex! Absolutely beautiful nib! 

Matador introduced the blue celluloid soon after Parker in the US, one, if not the first makers in Europe to use this colour. Beautifully made, the pen even has a small ink view in the front section! These were very early celluloid pens using new technology and materials The pen is actually sealed with blue silk threads in the front. All this is absolutely intact and clean! Only a large new sac has been fitted. The pen is fully working and ready to use and is an absolute stunner! Extremely rare!

Matador was at once time one of the most high end pens in Germany and a strong competitor to Simplo Montblanc and far older actually.
