"I have found the receipt. It is written on a note paper from "Red Lion Hotels".
Received from Hans Gille the sum of 400 dollars for
Conn Victor Cornet 217835 /4000 SEK/
After our mail exchange I have changed the text as follows:
Vad som talar för att att just detta instrument en gång tillhörde legendaren Bix Beiderbecke, som föddes i Davenport 1903 och avled i New York 1931, är att Bix ägde ett antal kornetter av märket Conn Victor 80A och hade ett eget sätt att hålla instrumentet med tummen pressad uppåt. Detta instrument har just slitage-avtryck av ett sådant grepp. På det medföljande originaletuiet har man funnit ingraverat initialerna L.B.B. Leon Bix (Bismarck) Beiderbecke. Museet är tacksamt för synpunkter som kan leda fram till ett definitivt fastställande om detta är just en av Beiderbeckes kornetter eller inte. Serienumret är 217835.
I try to translate it into English:
What points towards that this particular instrument once belonged to legendary Bix B, born in Davenport 1903 and died in New York 1931, is that Bix owned a number of cornets Conn Victor 80A and he had his own way of holding the instrument with his thumb pressed upwards. This instrument have wear out marks of such a grasp. On the original case are the initials L.B.B. - Leon Bix (Bismarck) Beiderbecke - engraved. The museum look forward, with thanks, to receive opinions which can lead to a definit statement is this is one of Beiderbecke's cornets or not. The serial number is 217835.
Here is my reply.
"Dear Mr. Carvenius,
Thanks very much for informing me of the changes you have made to the description of the Conn Victor in the Jazzens Museum. The new description is certainly an improvement over whatyou had before. I will post your response in the Bix forum and will let you know of any comments from readers and contributors.
How do you really know that the case is the original one for this cornet? Could you provide a photo of the case and a close up of the engraving?
I sent a PS asking for a close-up of the worn mark on the cornet.
Questions for cornet specialists. Did Bix have a peculiar way of holding the cornet "with his thumb pressed upwards"? If so, can you point out to photos where this way of holding is apparent? If a cornet is restored, would such marks disappear? Is it possible to tell if an instrument has been restored/polished? And after restoration, would such marks of wear be still visible or not? I imagine it depends on the extent of wear and the extent of polishing. Does the Bach Stradivarius in the Putnam Museum show such mark of wear associated with the way Bix held his cornet?
