From what i have had heard and read the GGTS Rev2 starts at s/n 550. The tube is the same as Rev1 from #459 which is the first with "To my friend". But the Rev2 from 550 comes with ad-cap instead of 4in1. The engraving on these tubes are a 20 mm wing on top of the tube, and The GG and To my friend on each side.
The nickelplated should start at 880 and was ment to go to about 1500. The engraving here should be wings and the GG in one line, and no tmf. Within this range there are some alu-tubes, (about #950-#1081) and i wonder if they should have the engraving with wings besides the button, the GG on the side of the tube, and no tmf. Can anyone tell if that is correct or wrong??
That is why i wonder about yours, Otello It seems to have the engraving like the nickelplated, but looks like the alu.
* It could be one of tha last alu-run, but did not get the nickelplated - or the nickel can have been removed?)
* my assumption t about the alu-tubes engraving is wrong
* or it is real rare
Would have been great to get the answer on this
