Would any of you guys know what gun this is? The screw sticking out the side is a make shift lever to unlock the action and allow it to swing. The lever you can see under the barrel is an extractor for the cartridge. Please see pics for more detail. There is not any mfg markings, not sure if it was originally a pistol or what the grip was originally the current grip looks home made. Its owned by a friend who asked me to help identify it, no idea what its chambered for but looks like maybe 22 short or 22long but those are just his guess.
