You can retrieve the vector of weights for a contrast from:
where n is the number of a wanted contrast.
Alternatively you can look it up in Matlab gui after loading a desired SPM structure.
Hope it helps.

Subject: [SPM] the formula in the T-contrast
Dear SPM experts,
I would like to know how to retrieve the formula I entered in the T-contrast in the first level analysis. When one clicks on one specific contrast , one can only see the contrast maps with ONs and OFFs in the design matrix. However, I would like to know the exact formula (e,g., [1,0,0,-1]) I entered. Can someone tell me how to recover the information? Thanks!
