Send it back to the factory or a trained professional
Would have to see how much damage was done with the reblue. If this was a restoration, instead of a reblue, the gun could still bring over $1000. If it is a typically wheel-buffed hot-salt blue - which is totally inappropriate for that gun - value is maybe $400.
There is no fixed answer because it depends on how much work the gunsmith will have to put into the job and how much he charges. The gun will have to be disassembled and prepared for blueing. You should contact a gunsmith in your area and have the job estimated. Hint: for a JC Higgins gun, the cost is probably not justified for the value of the gun.
use the ray gun or the thunder gun
eBay is the best way to sell
a gun rack
The reblue, even if factory, destroyed any collector value. As a shooter, it's worth about 100-300 USD, depending on how good the reblue is.
If you have a good spray gun and a small compressor,that's a better way.
1. See what it sells for (and has sold for) on GunBroker and similar gun auction sites. 2. Ask in a gun forum.
the best weapon will be thunder gun, ray gun, stakeout, and more. Any one of these u can kill them 1-2 shot kill.
Find the ammunition that it shoots the best.
Since the rail gun does not yet exist, there is no way to answer your question. Researchers are working on it, but there are no REAL railguns yet. Sorry-
It can be done by whipping a whip or firing a bullet from a gun.
