Many D2-3(99B) lines are ry-, but since the D2-3 element itself carries
ry+ the flies have wildtype eyes. So those stocks are of no use to you. 

In fact, the D2-3 insertion at 99B has two copies of ry+ according to Hugh
Robertson. We and at least one other lab tried to get rid of the ry+
transgene by ordinary mutagenesis in order to make a stock for injecting
ry+ transposons, but we were not successful. We didn¹t know at the time
that there were two copies there!
