I have recently re-acquired a Statesman Snorkel in pastel blue after a gap of over 50 years. My last one which was a present from my parents on getting a scholarship to senior school in Edinburgh, was used as a dart by the school bully. I had been looking for a good one with a broad nib for some time but at a reasonable price. My "new" one is in lovely condition, has just been serviced and has had so little use that it is still showing the sales price of 5 pounds 7 shillings and sixpence (including purchase tax). As the lettering is half worn, I would prefer to remove it completely (unless that is sacrilege in penworld). What is the best way to do this with zero damage risk to finish of pen. I had thought of brass polish but I am worried that I might leave a dull patch.
