According to 'Fighters: Volume Three (Warplanes of the Second World War)' by William Green there were several captured examples held by the Germans and others completed at the Danish factory by Mid-1941 and thereafter used as trainers for the Bf110 units until attrition wore them to nothing. The discussion of the G1 was paraphrased also in 'Flying Review International' April 1967 where the same author repeated the claim.
