I have a TM1 with an aftermarket 34" tapered rib barrel that has been fitted and worked by Wilkinson and stamped.. The receiver, iron and wood have matching ser #'s and the trigger is a coil spring . The barrel has a 740 bore and 36th fixed choke and small hole porting by Wilkinson. Bluing is good and no cracks and only a few normal handling marks. Gun comes in a John Hall combo case.
