Hi,
Anyone know how to ID a 1275 EN40B Cooper S crank if the casting numbers have been ground off in the wedging/polishing procedure? I missed out on a crank because I was not able to confirm that it was an EN40B crank - anyone can stamp it EN40B/AEG480. All I had were pictures, so wasn't able to see in person.
Any physical traits to separate it from a later reground America or a AEG623EN16 crank?
Even if it were an EN40B crank, is there a way to confirm it without the services of a metallurgist?
Thanks,
Joe
