We do not store any initial values, but the current values are in the various objects. For example, see the atom object for coordinates. Histogram object for scale factor/instrument terms,... There may be some items without a formal API access. For them you need to go into the .data objects (see the GSASIIobj section for a description of of those structures), but everything is there. ESDs are in the Covariance data item.
If you want initial and refined values, you will have to store values before and after yourself.
