Not sure old boy. Was the '13' the one flown by him in France, in 1940, still flying today in Canada?
BTW, the kit is not worth getting - unless you want the decals - as it's the old, former 'Frog' moulds. They were almost acceptable back in 1969, when first released, but the kit is very inaccurate in a number of areas, and takes quite some work to get it to look even partly acceptable. If it was around £15, it might be worth the effort, but at Hasegawa prices, forget it - get the Eduard or Dragon kit instead!
