Nope: actually I did not read the description, because I'm quite familiar with the actual amp. What I noticed was that it says '59 before "Marshall “Plexi†Super Lead 100 (BRIT PLEXI)," as if the amp was a model from the year 1959, and if you look, you'll see that that's where there year is listed for all of the amps above it and below it: '65 Marshall JTM-45, '71 Park 75 [bRIT P-75], '58 Fender Bassman, etc. Hence it should not say '59 before Marshall “Plexi†Super Lead 100 (BRIT PLEXI). So yeah, what I wrote seems kind of goofy because I didn't notice that the description makes the distinction between year and model number, but that doesn't change the fact that it shouldn't say '59. Probably meant to put '69 there. Anyway...

A couple of minor notes: that's not an S6616 in the photo, and there were no Marshall amps in 1959 (although that's the model number for the 100-watt plexi). Thanks for this, though!
