Runic inscription

On the front:

Stenfast let . . . . stone after Björn, his brother
: sta infas - r : Ii - . . . in : at : b]iar[n] - u [u]r... i[n]

On the side:

. . . . after Björn and Arnfast(?)
. . . at : bia - [n a - . . . rnfas]...

Runecarver:

Ärnfast

The ornamentation on U 31 and U 43 is almost identical. Both also have a signature page on the side with a simple dragon tied with a shackle in the shape of a ring.

We can probably find a counterpart to the bird on U 31 on the Böksta Stone, runestone U 855 in Balingsta, which is probably the work of Ärnfast.
 

Today, what remains of the runestone stands beautifully in a sheepfold, but it is no problem to go in and take a closer look at the runestone. Somewhere nearby are the missing parts that will sooner or later appear.
 

In the fall of 2021, it was difficult to see the painted chippings. The paint was almost completely gone.
