You have two choices. Attempt it yourself "see the link below for the parts manual" or use Crosman service to locate a repair shop that repairs old air guns. (see the link #2 below)
Crosman made the model 130 in two variations the first one had walnut pump and handle 1953-1954. The second version had a metal pump 1955-1970. For a time Crosman did not put serial numbers on original parts. ( I had to do some reading to find this fact out.) Yours may be one of these models. I also own an old Benjamin that has no serial number. Reference Blue book of airguns 7th edition.
The Crosman 130 was made from 1955 to 1970. It is no longer on the market. The condition and demand determine the price you will pay. Anything Goes. However if you had one that was brand new and still in the box it would sell for around $85 today.
See the attached link below for the parts diagram. This pistol was made between 1953-54. Crosman no longer has parts for it. However they offer a free locater of shops the repair Crosman antiques.
Crosman made a V-350 from 1961 - 1969. I do not believe they made an I-350.

I believe you are looking for a Crosman model 130. It was made for Wards between 1953-1970 by Crosman. You can try the web or gun shows.
