3. The top of the breech forks have neat narrow horizontal flats that exactly meet the same line; a neat and lovely styling detail that continued onto the first generations of the post-war, ball-sear model 27.

nice finishing touch purely for aesthetic reasons.milbro continued this for a while,the breech on an air rifle can look quite ugly,not in this case.
