.020 over Wiseco piston for 400cc

[idiotboy]

Found this while looking in the shed for an engine stay.It's in the wrong box,but has 427 or maybe 417 cast in the wrist pin boss.Ring set # 3209LC,missing circlips.I bought this over 10 years ago while rebuilding my 400,before I found out myb cylinder was bored bigger than this already.Anybody need it ?
