Pre-64 Model 94 Scope Mount ID|General Discussions & Questions|Forum|Winchester Collector

My old beater ’55 Model 94 has had 4 holes drilled and tapped on the let side of the receiver for a scope mount. I am thinking about adding the scope mount and a period correct scope to play around with. Can anyone identify the scope mount that would have been installed by looking at the placemenbt of the 4 holes? Thanks
