You got me thinking on that on! I do not know.
Pink Glow is a synonym for Dolgo (according to Mr Habibi @ Keepers).
As for it being a M. pumilla, I note that online RHS plant finder its
listing for it don't go down to the species, just cultivar. (http://www.rhs.org.uk/RHSPLANTFINDER....asp?ID=169623)
How is that for a non answer!

Well Cliff thank you and sorry for the headache! The funny thing about
this malus pumila Red Glow and what attracted me to this little tree
is that, according to Robert A de J Hart, this crabapple's leaves are
red in summer and turn green in the autumn! But thank you again and if
I find it I will let you know!
