Rene DeVos against Danish boxers

[DanskBokseResearch]

Any boxing historians who can help me with details on the record of belgian old-timer Rene DeVos?
According to his record he boxed Danish boxers Dick Nelson, Chic Nelson (twice) and Hans Holdt. I do have detalied descriptions on the fights with Chic and Hans, but have diverging information on the result of the Dick Nelson fight in 1919 in Antwerp.

Any help?

Thanks
