Because of the colour, I suspect that ‘ Winnie Davis Climbing’ may have been be a sport of the salmon pink Winnie Davis (hybrid tea, Nanz & Neuner, 1902) and not as shown, the white Winnie Davis (Tea, Little 1892)

Climbing Winnie Davis H. T.
(Cal. Rose Co., 1913)
A true CLIMBING sport from the bush sort, Winnie Davis: of extremely strong climbing habit and very prolific of bloom; well branched and foliaged from the ground. Bloom of fine size, with buds and half-blown flower shaped and moulded in absolute perfection; of nice substance and moderately full. Color, salmon-pink, shading to shell-pink and perle. This is undoubtedly one of the greatest acquisitions to the climbing rose family yet produced. 50 cts.
