In mid 1934 Parker began marking most pens and pencils with a date code, both the barrel and the nibs were marked, but lacking a date code doesn't necessarily mean that the pen was made pre-1935, since many imprints have been worn off with use.
V-CC member Nick Tithecott has a part of the packaging which once contained 2000 "Jackson Rd." transfers; this bears the date December 1922 and may well have been the first batch of formal transfers for the fledgling company.
They were based 39 Landseer Road prior to 1922, when the company moved to 2 Jackson Rd, Holloway, London N7.
And since the gold part of the microlayer can be as thin as about 0.003–0.3 micrometer, the amount of gold used in the process is incredibly low.
Electroplating chemically adds a very thin layer of gold to the base material. The process involves physical vapor deposition of gold (PVD). According to Parker a microlaminated surface of 1.3 micrometer has a "service life" equivalent or exceeding that of a 10 micrometer gold plating.
Using the words "Quality pen", one letter per year, followed by a quarter marker, allowing for dating within a ten year span.
So far the earliest date coded pens found have had the code NL for 1979, and all of these pens were made in the US. This is a standard for shortening the description of pens, either for personal use or when offering pens for sale. But to reach a 93% visual accuracy compared to traditional gold plating, Parker uses a 3 micrometer layer of which 0.4 micrometer is 14K gold.

Gold plating is usually a thinner layer than the above. In 1986 Parker patented a process, developed together with Jamers Snyder of the University of Wisconsin, for depositing microlayers of gold and titanium nitride to create the glow of gold but the durability of chromium.

To be stamped 12K or higher the layer must equal at least 1/20 the total weight of the item. Signs of wear on the nib or light discolouration of the section or around filling lever or button filler. Clear signs of usage, but still a better than average pen.
