I have been interested in Baker's since I watched the Richard Sharpe series.  It's on my list of neat rifles I would like to have.  I have seen finished rifles on TOW occasionally with or without the bayonet.
There are 2 other rte.s you can go, other than TOW. 
!. The Rifle Shoppe ( Michael's gun ) $2000.+ ( finished ) $900.00 (unfinished )
2. The Discriminating Gen. ($468.) or Loyalist Arms ( $552.)
These Bakers come un-rifled & W/O the touch hole bored.
This is the rte. I went. I got mine from DG ( NOTE _  this Co. is SLOW & Cust. service is POOR (IMO ) rec LA.) I got the gun knowing it would be a "project" :mozilla_tongue: The 2 major areas are:
1. rework lock.
2. re barrel. ( gun is now in WV getting it's new Bbl.
hopefully I will be ready by the start of the season, this spring. [-o<  [-o<  & that it will be worth the effort. 
NOTE - replacement parts are not avail.
