Even though that gun was made by Wiinchester and is basically the same as the Model 1200, the trigger guard and stock are different and those parts from the Model 1200 will NOT interchange. There is no commercially available pistol grip kit for the Sears Model 200.
Your rifle was made for Sears by Marlin, and is a model 336C.
This 22 cal pistol was made by Crosman Co for Sears. It is a model 130, Mfg 1953-1970. To assess the value I need to know the condition of the pistol, is it excellent, good, fair, poor. You can find the manual for the 130 on the Crosman web page see the link below
The Sears model 2200 is the same as a Savage Model 80 Series A.
Go to gunpartscorp.com . There may not be a Sears model 5. Look at the High Standard and Marlin rifles to find your model.
