This is really a very nice pistol. It was made between 1964 and 1985 in 3 different variations. In good condition it is worth around $40-$50 plus 20% for the original box. If it is the rare chrome version you can add 200% to 400% for the salesman sample. For the owners manual see the link below.
Two things you need to state. 1: The condition of the gun. Excellent, Very Good, Good, Fair or Poor. 2: Is it in working order? Crosman made 2 different models of the T38 a .177 Caliber and a 22 Caliber. Your pistol could be worth anywhere from $30 to $90 and more with the box. BUT I need the above information to give you an estimate.
around $135. It was made between 1950-54. and its a .22 caliber. If you have the original C02 cylinder spare tank DO NOT USE IT. Crosman had warned owners. See the link below for the Crosman 112 owners manual
The model 600 was made between 1960-1970 it is a .22 caliber pellet pistol, in the condition you describe it is worth in the area of $275. Plus, add 20% for original box and papers.
The Crosman 38T Target came in .177 & .22 caliber. It was manufactured in 3 different variations over the years. (1964-85) In excellent condition it is worth around $90 plus another 20% for the original box.
It would be worth between $65 - $75
it would be worth $40 to $50 in working condition (Still holds C02 no leaks)
The model 112 was made between 1950-1954 it is a .22 caliber air pistol (see the link below for the owners manual) In good condition it is worth around $85 - $110. Crosman warns that if you have the original C02 Spare cylinder, Do not use it. The Cylinder also adds 30% to the value
