Wore out three sets of tires already!
I can't read the decals, but based on a serial number search and 1980 catalog, this appears to be a Cardinal Red Varsity Sport. Evidence is that the rear derailleur is a Huret GT-510 and the overall shape of the decals matches. Similar 24" models of that year were the Deluxe Varsity, which had a front freewheeling arrangement, and the Collegiate Sport, which was a 5-speed. In person, this bike looks like a 27" bike that was left in the rain and shrunk. The photos don't really convey that, except it looks to have a huge chainring. My grandson will be big enough for this bike before long and be able to zip along on his own road bike.
That is a Varsity since it's the only model 10 speed that Schwinn produced with the blade fork. The MR serial numbers denote a 1981 build at some point, and a few in 1982. So check the date on the head badge for the actual build date. There was a strike at the end of 1980 that lasted into the first of 1981 so no bikes were built for 13 weeks, or a little longer. Hope your Grandson enjoys it as much as I enjoyed mine as a kid.
