@nsussf57 Steve,
Here is unsolicited input from me...
There are three price points for selling:
A. What the item is worth, actual value. This may take a while to sell at actual value especially for a high priced rifle such as a Heym.
B. The price an item will sell fairly quickly at. This is 85-90% of the above fair price.
C. The price set when one needs to pay the rent. Probably 70% of the actual value.
How soon do you want or need to sell it?
Is your price at or better a little below what very similar items are listed at?
Once folks return from SCI there may be someone interested in your rifle.
I prefer Guns International for selling guns. It is not as fast as Gun Broker but the cost is about $20 per gun. For me, they always let me relist for free after each six-month period.
Otherwise, I had JJ Perodeau sell a double for me. He charges 15% but... When one buys a double from JJ, they can be sure it is a good rifle!
