I too love the early Hollands and Binko's gun in particular but 400N is right, the 1920's gun was made at the zenith of of the Holland factory's gun making abilities. That era Holland sidelock's design, form and funtion is timeless. The 1950's gun is sst, assisted opener, all the bells and whistles. If there are other like guns for sale then it is time to compare measurements, condition and price.
