This pen might also be the Scripto 100, or even the Scripto Dollar Pen; it cost a dollar, and had on the shoulder of the clip a little 100 impressed by way of a MSRP indicator. It is, in all aspects, a very low-end fountain pen, and I suspect that it is exists mainly to catch the still-running wave of interest in Parker’s hooded pens. There is one interesting technical aspect, which lends the pen one of its possible names. Since it lacks any means of checking on the available ink supply, it was equipped with a reserve to abolish the spectre of running out in mid-paragraph; a little bit of sponge thrust into the back end of the ink sac. If the pen ran dry, working the lever would force a drop or two out of the sponge, and in theory allow the all-important message to be written.
For all that it is a very painfully cheap pen, is it actually a slightly better writer than contemporary Wearevers. This is damning with faint praise, of course.
