Got a few exonumia-type mysteries here I was wondering if anyone knew the answers to. They were purchased in a bulk lot of Swiss cantonal coins, and may have been confused for cantonal coinage by the original owner, but these three definitely aren't coins.
#1: City of Chur, brass. Doesn't say anything except "Chur 1842". There was apparently a Federal Shooting Festival in Chur that year, and the arrow seems to indicate some sort of archery or shooting theme.

#2: Canton of Fribourg, bronze. Obverse the cantonal arms, with legend "SOCte. CANTle. DES CARB. FRIBOURGOIS (Fribourgian Cantonal Rifle Club?), reverse a Swiss Cross with legend UNION FORCE (Union, Strength). I'm probably way out on my "Rifle Club" guess; it could be a Trade Union piece. Neither BabelFish nor my French dictionary are being particularly helpful in this case.

#3: Canton of Solothurn, brassy. This one is the most obviously "shooting-related" piece. On the obverse, you've got crossed rifles behind the Swiss coat of arms, on the other, EIDs FREISCHIESSEN IN SOLOTHURN (Federal Free-Shoot in Solothurn), 1855.

I guess I'm at a loss as to what exactly these are. They're obviously not prize medals for the shooting festivals; the famous "Shooting Thalers" were the main prizes. So what were these? Participant medals? Souvenirs for spectators? Tokens? Any help or opinions appreciated.
