Thank you for the response.
By all appearances it looks to be the original (second) addition published in 1884 with the supplement. (only date or number on the info./ printers page is 1884) The cover is maroon fabric over board with embossed gilt lettering. Its approximately 3 1/2 inches thick and has advertisements in the back .
Also thanks for letting me know about the online version and that its a good reference book. I'll add it to my library shelf and read it online until I have it restored.
