That's a great looking Mark Twain cob Brian. I like the thick walls on the bowl. Here's some measurements on the diameter and inside bowl depth:

Chamber diameter: .75 in/19.05 mm
Chamber depth: 1.625 in/41.275 mm

I've never used a filter myself, but you may want to go ahead and smoke a few bowls with the filter, then remove the filter and smoke a few more bowls of the same pipe tobacco to ascertain if there is indeed a difference.

Again, nice looking cob my friend
