The 541S in excellent shape is selling for around $700.00 USD, The T with the match chamber [early production] only slightly less. I have one of each, and they are truly accurate rifles. The THB is worth less than these, since virtually none came with the match chamber and the fully adjustable triggers that were on the early rifles, My guess is about $400.00 or a bit more if it is pristeen.
