I occasionally find them at gun shows. But the Mark1 only requires a common 12 gram powerlett to work. This can be found anywhere. The Gold ones are just a color. They is nothing different between them and a silver one.
For a rifle, you could get a Scope, Case, sling, cleaning rod (.177 caliber) Crosman Pellgun oil. or a red dot sight and targets. For a pistol, get a holster, case, cleaning rod, pellgun oil, red dot sight, extra cylinder if necessary and targets
If you are asking about a BB or pellet gun then try using a drop of Crosman Pellgun oil rubbed into the pellets or BB's. This will lubricate the pellets and the barrel. Don't over do it.
Crosman 38 C combat In very good to excellent condition it is bluebooked between $75-$90. Add 20% for original box. Add 200%-400% for the chrome salesman sample pistol
NO never use any oil other than Crosman pellgun oil or RWS air gun oil. Other oils will slowly destroy the seals
Purchase Crosman Pellgun Oil. (NOT Another kind) put a few drops of oil in your pellet tin. Do not flood the pellets. roll the pellets around in the oil. This will increase your power and speed.
First of all DO NOT use regular oil on an airgun, Always use "air gun oil" like RWS or Crosman pellgun oil. Regular oil will eat the seals. You did not state who manufactured this pistol. I'm going to guess 'Crosman." Oil the hinges, Put a drop of oil in the breech and the barrel to coat the inside. Put a few drops on a small rag and wipe the pistol down. That's all that is needed.
The Crosman Bullseye Target model 105 is a pump pistol made between 1947-52
Typically the pistols are "12 gram" powerlets although there are exceptions. The owner's manual will tell you.
Your 38C Combat is a replica of a S&W 38. There were 2 variations made. It was manufactured sometime between 1973 and 1981. The value can not be determined because you have not stated the condition of the pistol.
The Crosman 357W is a pellet pistol not an Airsoft pistol.
See the link below for the Crosman 1300. It is similar to the 1322 model.
The Marksman doesn't require much cleaning. I suggest you purchase Crosman pellgun oil and put some on a cloth and wipe down the pistol. Open the breech (Barrel) put a drop of oil on a q-tip and run it through the barrel. Do this until the Q-tip is clean. DO NOT use any firearms cleaning agents on the pistol or it will ruin the seals in the gun.
