Here I am answering my own question as know one else has been able to come up with anything. I posted this question here a couple of months ago. I'm typing this to help anyone out in the future. The gun is apparently a FEG (Femaru Fegyver es Gepgyar. This is the name of the place where the factory was, or the name of the factory itself. They made a more popular model called a "continental". A continental is worth about $300 - $400 (in 2007). I'm not sure if the "Monte Carlo" is more or less valuable as it may be more rare of an item. FEG is more into handguns now, but has made a wide variety of firearms over the years. Hope that this helps anyone.
--------------------------
This Monte Carlo Model 1929 shotgun was designed by famous gun designer Rudolf Frommer in Hungary during 1926-29. The Monte Carlos were manufactured in small quantities from 1929 to cca. 1939 by Fémáru Fegyver- és Gépgyár R.T. Budapest. These shotguns are fairly rare in the USA, your 55160 is the highest serial I have seen. Well made, high quality guns, rare and collectible.
It depends on the year, manufacturer, and condition, but if it's a genuine antique and in good condition, you should be able to get at least $1,500 for it.
That is impossible to determine without knowing the manufacturer and model of the shotgun.
$50-$100, depending on exact manufacturer and condition.
Not nearly enough information to make a guess. Need to know the exact manufacturer and model number as well as the condition of the shotgun.

Follow manufacturer's instructions.
The value of a Westpoint shotgun will depend on the weapon's condition. If in excellent condition the shotgun is worth $500.
SILE was not a gun manufacturer but rather simply a NY importer of guns. Your shotgun was no doubt made in Italy and sold for approximate $450.00 when new. Depending upon condition it is probably worth about half that now.

The value of an 11-87 Remington shotgun depends on the condition of the gun. This shotgun in excellent condition sells for between 50.00 and 625.00 as of 2014.
It depends on the browning model of shotgun you are asking about,and the condition it is in.
