help with miyata road bike frame size

i’m looking at bidding on this miyata seven twenty road bike, but the frame size description looks kinda odd:

50cm from bottom bracket to the seat, 51cm from the seat to the stem, 57cm from the stem to the bottom bracket

the frame looks much bigger than as described?

yeah, my guess is more like ~55cm. 100% not 51/50cm. perhaps it was measured from the inside of the tubes.

also, does that fork look bent? guessing its just because of the angle of the bike in the photo.

id say thats a 55/56

obviously not measured centre to centre.

that’s what i thought too around 55/56 cm frame.

too big for me, I was hoping it was around 52/53 cm frame
