Thanks for all the info.

I did find a number on the crank, 2G128, is all I can see. The best I can measure the big end is 1.5985" with me digital verniers.

It would be a 12G1287 or 12G1288 then, small journal 1100S (not Cooper S) crank. EN16 material.
Should be fine.

Thank you Kevin, I should clarify and confuse.
Regarding markings and part numberrs.
Markings on the rods AEG177 & AEG521 are for part number AEG520
Marking on the rods AEG625 is for part number AEG624. EDIT: I am using a set in Slidey.

I like most go by the markings on the rod.
