Yeah. Lakland is fairly vague on their website. Simply stating:
"Lakland 44 and 55 instruments feature a solid chromed bridge plate with all stainless steel parts (saddle, screws, springs) to prevent rust and corrosion throughout the life of the instrument."
But as you can clearly see in @Thom Fioriglio photo, his 4-string saddles are different bwtween the Sklyline and US models whereas in my photo, the 5-string saddles appear to be the same across the board.
Could simply come down to what they had available on the date of manufacture.
FWIW
My first gen Skyline has satin saddles. Also has other US components, I believe. Part’s is part’s, they say.
