hi has anybody seen the steam whistle on ebay item no 11028304250 its a 5 chime step top he says it is made of cast iron with no  markings at all if you look at the chime steps they start from the left and go to the right.most all of the 5 and 6 chimes steptops that i have seen all the steps start from the right and go to the left even the rough looking ons that were shop made.if you go to mike doughertys md whistles web site you will see all his step top whistles the steps start from the left and go to the right just like the one on ebay  i ask hem why he said because of the patened rights he did not want anything to come back to bite hem so he changed the steps to go the outher way.does anyone think this is repo
