chap, I am going to guess they are going to send to Deer Creek Products for Parts due to CVA sold most to all of there sidelock parts to them
From there FAQ.
1. Do you still make, carry or repair Side Lock model muzzleloaders like the Hawken/Kentucky/Mountain or Bobcat?
Answer: We Discontinued Side lock muzzleloaders both Pistols and Rifles in 2004 due to lack of demand. We will still continue to offer Mainsprings, Sears, Wedges and Bolsters screws thru the year 2010. Most all other parts have been sold to Deer Creek Products, a service center that is located in Indiana. Deer Creek Products can be reached at 765-525-6181.
