Quick and easy. The first post-64 Model 94 was serial 2700000.
The last pre-64 Model 88 was serial number 148,858. A guns value depends greatly on condition...ballpark figures for the value of a Model 88 in 284 Win. in 95% condition would be about $900 for a post-64 rifle and about $2000 for the pre-64 as the 284 was only available in the pre-64 version for one year....The most noticable difference between the two would be the stock....The pre-64 stock had diamond cut checkering while the post -64 had the oak leaf impressed checkering.
