Set 101A is the Märklin development of the 1914 Meccano set 1a making a combination with Set 101 an outfit similar to a 1937 Meccano Set 5. The Flanged & Grooved Wheels with large tyres are much better and more versatile than the tinplate Meccano Roadwheels   in Set 5. One part 60/7 has been replaced. I could not find a picture of this set but the picture of Set 101 was a useful guide.The wheels are mounted on the original mounts which were fastened to the card base. Some of the clips securing the other parts have been replaced. Note that the aluminium flexible plates are painted blue on one side only - a feature often used on models.The position of the Windmill Sails is pure guesswork.
