I do not have the records,but I give you a simple method to test the accuracy of the transfers:as many of the records of the Hot Five & Seven,and of singers accompanied by Louis were recorded at 80-82 rpm,you have to check with a real instrument if the record plays at the correct pitch.The easiest tunes are Muskrat Ramble (Aflat),Cornet Chop Suey (F,NOT E FLAT).I am curious to hear from you the results of the test.Sorry for bothering with my digression from Bis.All the best,Veniero
