This is one of the wonderful National Security Fountain pens made in the 30's and 40's in the UK. They are a top quality pen, made from good plastics with solid trim. This one dates from around 1935 and is finished in the incredibly rare Grey and Green Lizard Skin which has retained much of its original lustre. The pen is in overall very good condition with minor wear marks. It is fitted with a lovely Medium Flexible 14ct gold nib.
It has been fully serviced and is ready to go!!
Note I have described the finish as Snakeskin on the write sample, my mistake, it is definately Lizard skin which is a lot finer and more detailed than the Snakeskin finish.
