OH yeah,,, years ago John Pep, Joe Wotka had done some very good research. Test what the HR was made of among other things. Rob Wells and the both of them also computed out what IF a HR was engraved in the flat,, and then rounded,, what would happen to the engraving [ spoiler alert,,deformity was almost nil]...
Hope Joe see's this and can remind us of the tests exactly and what he thinks so far of Antonio's theories. Thanks guys..,G..
