Nice carbine! I have an "Arlington-Ord" Saginaw and I believe your barrel stamping should read Arlington, VA rather than Arlington, Wa. Mine has a Post War cast front sight (unmarked) and is probably the same as on yours. Even with the repairs, your stock has quite a bit of value to it. Mine has refinished metal and was shipped with a new replacement stock which is very nice, but does not have the "character" to it that yours has. A lot of the "high wood" IR-IP stocks were cut down to "low wood," but yours is still intact.Welcome to the forum! - Bob
