The first one looks like a Gasser Kropotcheck(sp?) 9mm officer's revolver. It's a cut above the Belgian copies because it's an original Gasser made in Vienna, Austria.

The second revolver is a rather common Belgian pocket revolver. It could have been made in the early 20th century. Some of these Belgian revolvers are chambered for .320 which we call .32 Short Colt. Others are chambered for .32 S&W and a few were made to fire .32 ACP. It looks like your revolver has a broken trigger return spring and it might have other problems as well. Get it checked out before trying to shoot it. See if this revolver has any proof marks on the breach end of the cylinder. Depending upon the type of Liege proof mark it may be possible to narrow down the date of production.
