74880 vs. 6035 - an alias ?

[Philippe Hurbain]

An alias works for me too, but if someone has the courage to cope with this one, I opened the lamp, and made close-up photos...
You can get them here!
And I confirm that 6034 is the bottom part, the only one with an engraved number. 6035 is the middle transparent part (lamp support + dome) and 6036 is top part.
