"Alphy Flyer" Red Wagon

Hi.  New to this forum.  I have held onto this little red wagon from my youth.  I believe my parents bought it at a local Alpha Beta grocery store in the late 50s early 60s.  Instead of "Radio Flyer", it is an "Alphy Flyer".  I wonder if this was made by the same company, but for the Alpha Beta chain.  Has anyone else seen this type of wagon?  I am particularly interested in finding a replacement hub cap as it is missing one.  Any information or help to point me in the right direction would be appreciated.  Thanks.
