Well Ian, you should not feel bad about losing this one!
Story was this gun belonged to an interior BC trapper and it spent most of its life in a scabbard, hence the wear to the checkering - it sure didn't spend much time on the cleaning bench
Buttplate is incorrect, as well as the rear sight elevator I believe (although I am not sure which is correct as all three of my plain barrel FNs have different elevators!!)
Cocking knob is also not right - got any parts left Jack?!!
Some pics of FN 1900 #2038
yes, that is rust you see
and here is a group photo
Notice the difference in checkering on the forearms of the three early rifles
