Inland Parts in NPM Carbine??

     Need your help. I acquired an early NPM carbine (mid-July, 1943 by serial number) from an auction, the carbine appeared to be almost perfect. . . . .all early NPM parts as they should be except for rear sight (replaced in field?) and replacement stock (Winnie potbelly).  Here is the curious part. . . . it has an Inland type III slide.  Now I read in War Baby that Inland supplied perhaps several thousand slides to NPM in 1943, but if I have this correct, these were type II (semi-circle rear box).  Is there any way a type III Inland slide would be correct for this rifle?  Really appreciate your help!!  Thanks!

    This was a NPM carbine, which as I said, had all the correct NPM-coded parts for an early model -except for the inland slide, winnie stock, and adjustable rear sight.  Early model was based upon 

serial number (1,508,169), and from War baby, the starting serial number for NPM and monthly production numbers, which puts my carbine at mid-July 1943.  

     Any insights you would have into the inland slide issue would be appreciated, and do you have any thoughts on the winnie stock?  I just assumed it was a replacement, although it had a NPM recoil plate(?)

      Thank you. (you can discuss by private email if you prefer:   burrojack@mac.com)
