Don’t know about the 100, but the 88 is around the 150000 range.  You could most likely see some of the Pre 64 style up to perhaps the 152000 range.  Interestingly the first style post 64 stock for the 88 did not have pressed checkering on the bottom of the stock, and had the Pre 64 style grip cap.  There really is not a lot of information on the 88.  The Murray book is very questionable,  I found a lot of errors.  Most Model 88s are cambered in .308.  I believe that the .243 is rarer then most people believe.  Don’t see a lot of them out there compared to the .308.  Of course the .284, and the .358 have always been of interest to the collector.  I always liked the 88.  Even though it doesn’t get the respect it deserves.  Some day I believe it will.  A good book on these interesting rifles would shine some light on them.

Mr. Murray stated in his book that he thought that the number of rifles in eah caliber was the same per year.  An example would be that in 1957 when the .243, .308, and the .358 were chambered in the Model 88 Winchester made the same amount of each. This is just not accurate.  I have had the book since it came out.  It does have some good information.  Perhaps, it just needs to be updated.  The 160,307 is the end od 1964, not the start.  The 148XXX would be the end of 1963.  So, I feel that perhaps you can still find a early 1964 gun with a Pre 64 style stock up to the 152,000 range.  I would not be afraid to add one to my collection with that combonation.  Again, not alot of information on these guns.  There were several minor stock design changes through production that most are not aware of.  One example would be that a Carbine with the W in the grip cap would be very suspect.  They were not made in that style.  When I see one I am sure that the 100 Carbine stock was used as a replacement.  The Model 88 is a very cool gun that reminds me of a slick Model 70 Featherwieght.  The people that used them can’t say anuff good about them, and that says alot.
