It's not 'Souvenir de la Malmaison, Climbing' -- the canes are too bristly. SdlM is a Bourbon-Tea, and has the expected smooth canes with more widely-spaced hook-shaped prickles. I wonder if what you have is some other leggy Hybrid Perpetual -- probably something early, since later HPs had further infusions of Bourbon, China, and/or Tea in them, and so looked less like their Damask and Gallica ancestors.
Where did you get it? That can help narrowing it down.
