As stated I have a 1918 dated #1MK3*. I was given this rifle some 25 years ago in exchange for some work I had done for someone. The rifle has the original serial crossed out and another one stamped below that. On the receiver is M broad arrow M with a number 2 above the broad arrow symbol. The receiver, bolt sight leaf and nosecap all match. The bolt cocking piece is marked MA 42 and the magazine which is unnumbered has a Lithgow proof. Was this rifle a rebuilt WW1 pressed into service for WW2 by the Aussies? Overall shape is VG with a nice bore and blue finish at about 90 percent. What is something like this worth? TIA......
