Yesterday I went into an antique shop near my house and bought an ELG black powder percussion rifle for $100. I did some research and found that it was made between 1810 and 1853 making it 163 to 206 years old. I know it's Belgian but I'm not sure of the caliber or what it's really worth. The only one I've been able to find that looks anything like it was from 1859 and was in very bad shape but the seller was still asking $800. I'm hoping to get some more information about it as far as what caliber it is how much it may be worth and if I can still get the right ammunition for it. If anyone has any good information please let me know.
