As said (Crown) ELG (Star) is a Belgian proof mark, as is the Perron obelisk. (Star) "something" is probably the Belgian inspector's mark.
(Crown) JA&C is likely the maker or distributor's trademark.

It's action appears to be the Flobert "rolling block" which is kind of misleading, it is not nearly as strong as a Remington. Not shootable in my book, unless for the wax bullet loads of the Gastine Renette Galleries.
