The ± 1946 Brownie Target 616 is the outsider: close-up means removing the first meniscus, not add an extra lens. It's on a spring, very handy: you cannot forget it. Focus 5-10 feet and the picture is indeed sharper. The whole picture, also beyond ten feet... So the single meniscus is better than the double.

1946 (International)

1946 And the bridge at Nijmegen is still standing proudly.
My uncle has fallen in love with his (Finnish) nurse - he is a
shot-down (half-German)
war-pilot, they will marry and have a son.
My (Dutch) little brother is one year young,
and the (Canadian) Target 616 is still a modern camera.

Technical data about the rather obscure (American) Weimet war surplus, and an even better picture are on my flickr photostream.
