The link
http://www.ww2.dk/oob/bestand/schlacht/biisg2.html confirms that II./SG 2 received a bunch of Hs 123 in October 1943, almost enough for a Staffel (or enough for an understrength Staffel) and kept them until May 1944. There were two losses due to the enemy, one in December 1943 and one in April 1944.
It then again received four Hs 123 in November 1944 and one was lost in operations in December.
So Matti gave the two lattest losses, but the one in December 1943 might have been in Crimea.
