LOL. Yes it is. Sorry I couldn’t help myself. 
FWIW, the 105 drivetrain on this bike isn't stock. It came with 600, according to what I can glean from various unofficial sources on the web. The work done to assemble this bike was pro quality - two clues: all threads greased, and not overtorqued. The BB feels brand new. The BB spindle taper looks identical between the SX and this bike. Conclusion: BB has already been swapped. The dealer sticker on the downtube is "Kenwood Cyclery", who were very well regarded as a top-notch shop back in the `80s-`90s. I'm betting they did this work.
But I definitely got your message, my queen. Please excuse my impertinence?

Which bike came with 600? Celeste looks to be an ‘88 Sport SX that came wif Exage Sport. The Squadra had a nice mix of Italian goodies like that Ofmega crank [ I got the wrong line looking at the catalog earlier]those Universal ‘Squadra’ brakes (but with hideous levers) Ofmega derailleurs…….
