I have three EGs with 900,000+ serial numbers. After reading this thread I pulled them from the gun safe. No. 907,8xx (.308) and No. 925,0xx (.243) do not have fluted combs.

But, No. 967,3xx (.358) does have a fluted comb. LBC is 11K making it a 1959 rifle. This rifle also has a folding rear sight which appears to be original. Murray's book says the rear sight on the F was changed to a folding sight in 1959, so I'm wondering if this is the same sight. Which also leads me to wonder if Savage ran out of EG/R parts and used F parts where possible on late EG/R rifles.

Sorry, but I haven't taken the time yet to figure out the details of how to post photos. (I have read the info in the misc good info post.)
