Need a slip joint for my Colt shadowbox display

[bdev]

Hi guys & gals......I'm looking for a knife to fill a spot in my Colt display pictured below. I'm trying to narrow down my search so I thought I'd ask the forum for ideas.
I'm looking for a folder that would look as if it was made around the late 1800's. The guns are dated 1858 & 1873.
I'm thinking an old wood handle single blade knife that could pass for one made from that era.
I've got about 4 inches of space (across and up) in the lower left corner.

If you know of any that might work, please post.

Thanks.

Something with a heavy patina.

Definitly!

One of the current GEC boys knives, or Barlows.
Or one of the Queen Heritage series.

I think a Barlow pattern would be appropriate.

How about picking up something old?

It can't be an ebony boy's knife though, the urge to open the case ever ten minutes to play with it would be too much.

Yes.....it must be an older knife with some wear to it. I'm not looking for a new knife.
