Here is yet another titanium prototype FP but what makes this one distinctive is that its barrel is without a tassie and dimpled like the stainless steel Flighter model.
Credit for these pictures go to Tsachi Mitsenmacher with the pen belonging to Israel Zigerson, whom I gratefully acknowledge. Mr. Zigerson reports that the weights are:
Cap 4.921
g
Barrel 3.862
g
Total 8.783
g
With a total weight of 8.8 grams, this is one of the lightest pens around, second only to the prototype titanium 75 with flat tassies. The difference is barely two-tenths of a gram!
