Sadly, no I live out in the sticks, and everything for me is sight unseen.Any chance you can get your hands on one? See if there is a dealer within 50 miles or so and go check one out. If you look on Wildwood's website, when they have listed a Jr, they are typically in the .81-.84 range (thickness at 1st fret), so a med/slim size.
Here's one they have right now, .84 at the 1st
