Contact Crosman service department the same clip is used in the current model 3657 pistol.
See the link Below.
I can not find any reference it any Catalog on a Crosman model 37 pistol. Crosman makes a 357 version and a 338 version. Check your information again an re-post your question. ( it is possible that my catalog's are missing this model. )
Crosman doesn't give any information about distance. You will have to experiment on your own.
357 is not evenly divisible by any number, except 1, 3, 7, 17, 119, and 357.
Is this what you are looking for? (See the link below)
Any .357 Magnum revolver (this does not apply to automatics or any other type of firearm) can fire .357 Magnum and .38 Special cartridges.
I believe Crosman never made a model B661 (But I may be wrong) I've searched the web and 5 different Catalogue Airgun books and can not find any reference to a Crosman Model B661.
Any .38 ammo can be safly fired in a .357. +P .38 loads do not exceed .357 pressures.
Do not know of any Colt factory service manuals on the web for download. For sale, maybe, but, you will have to spend time doing internet searches.
They were made by both Daisy and Crosman. Any BB gun model starting with 799 was a Daisy and any BB gun starting with model number 126 was a Crosman.
I don't believe Crosman ever made a model 40 rifle. I have no reverence to any model by that number made by Crosman. However they did make a model 140 from 1954 to 1968 in four variations.
No they are Smoothboar.
Both Crosman and Daisy made airguns for sears under the JC Higgins brand name. Any sears model air gun that started with 126 was made by Crosman. Any air gun model starting with the numbers 799 was made by Daisy. Here is an Example: Sears model 126.10294 was made by Crosman and is really a Crosman model V350
