The Easy Way: Crosman Offers a service to locate repair shops that repair older Crosman Airguns. See the link below. My Way: I own several Crosman 38T and older 357's I've rebuilt several. Seal Parts from the 38t were used in the design of the 357. Open the link below and then download the Parts manual for the 38t and older 357 and compare the seal part numbers from each pistol and you will find several are the same. They even began with the number "38". Crosman no longer supplies parts for the 38t or 38c but they do have parts for the 357 (Same parts used on both) So you and call customer service and order some of the 38 parts listed on the 357. I was able to rebuild two 38t's this way

Crosman never made a model 35T. They made a model 36 and a model 38T. The original box adds some value to the air gun, but you need to state the current condition of the pistol if you want an answer. You will have to give it some sort of ration like Poor, Fair, Good, Very Good or Excellent condition. Also state if it is still working. Without more information it is not possible to answer you. Check your pistol makes sure of the model number.
