Rivarossi HO Santa Fe 4-6-2 Heavy Pacific Locomotive #3423, Excellent With Box

(Box is from the 1990's, while loco model is from the 70's.). Made In Italy. Take a look at the photos (enlarged) and see what you think. All factory-installed detail parts appear to be present except for the cab handrails (see 9th photo), as loco looks like it has beenvery gently run!
