I am glad you liked it...
Those moments are what it is all about.
Buy a nice bit of the ERR match and dedicate a pipe to it. That will increase your enjoyment of the blend quite a bit.
I will also encourage you to pick up a tin of Wessex Burley Slices just to see how it compares.
That is supposed to be the closest that you can get to Edgeworth Sliced. (Which supposedly ended up as a somewhat different recipe from ERR - but they were still very closely related)
Edgeworth was once considered an OTC tobacco and it was available in the large 14 ounce tubs in recent times.
The Edgeworth brand goes back many years, however, to the time when they were blended by Larus & Bro. Co from Richmond, Virginia. Edgeworth Sliced and its variants are among those great old time American classics such as Prince Albert...
(I've just read that Larus existed independently from 1877-1968 when they were bought out by Rothmans. "The House of Edgeworth" continued to operate until 1974 when production was contracted out and facilities in Richmond were closed down. I believe it survived in modified form until the mid 2000s, ending its life as a Lane product. If there are other versions of Edgeworth out there, there's no information about it online. I don't know when the Edgeworth Slices or Edgeworth Ready Rubbed were introduced but I think they were the signature Larus brand so they could've been the original line of tobacco they offered. I've got a tin from the days before bar codes and they were certainly well established as a national brand before then)
"This small tobacco company, based in Richmond, Virginia, received national recognition with Edgeworth pipe tobacco, which then became the international hallmark of the company. By the 1930s, Larus had expanded to manufacture cigarettes, operate distribution centers outside Virginia, sponsor national radio programs, and manage local radio and television stations."
