PH4

If we are talking about modern scopes, I havefound the Swarovski 3-9x36 to be a good compromise for " period " rifles.

Small objective for low mounting, great optics,inch tube so it doesn't overpower the rifle, and great value for money at the price.

Otherwise an 4x32 early West German Ziess DIATAL, if you can find a good example for around $4-600
