Siemens. Also, the GE SS is probably not listed for ITE/Siemens. You'll have to check the documentation. Almost all SS units require two slots (either plug on units or dedicated breakers).
ITE was bought by Siemens... as documented here »www2.sea.siemens.com/Products/Re ··· dcenter?

Siemens AFCIs are specifically marketed for retrofit, given the nature of protection they provide that's especially needed in older wiring.
