Opening up an old English gun case is like stepping through the looking glass: You tug the leather straps, push the lock to the right, and the lid opens onto another world.

That’s why these original double-rifle accessories so cool. The seller claims that they came out of a case for .350 Rigby, but think they would go with any Rigby double barrel rifle.
As far as BUYING/SAVING $ on eBay goes:
Use a site like Ebuyersedge.com to set up saved searches. You get an e-mail whenever a matching item is newly listed. Especially good for “Buy It Now”s that are priced right.
Try a misspelling search using a site like Typojoe.com to hopefully find some great deals with items that have main key words misspelled in the title. Other interested buyers might not ever see them.
If you see an auction that you want to bid on, use a sniping service such as Bidball.com to place your bid for you. It’ll bid in the last few seconds, helping you to save money and avoid shill bidding.
