I would break the items up , and sell them individually -if you want more for them wait till closer to spring time when interest in turkey guns are greater
We can't sell firearms here, but you should be able to get $600 for the 1187 if its in excellent condition ( spring time) on gun broker
The chokes and ammo can be sold here , or the choke on eBay , a good rhrino in a desirable dia. Will get you at about $70 or more depending , the nitros you will get full price for since they are hard to come by
