Hi, welcome to the forum!
A little chaotic post, but if I get this correct:
pass - pass - 1
♣ - 1
♠
pass - 2
♠ - pass - pass
3
♠ - Dbl*
I wonder what that East guy can have (the 3
♠ bidder)

.
Anyway, I usually play reversed lead directing Doubles when opponents cuebid our suit. So:
pass = you can lead the suit
Dbl = don't lead our suit
