That's a beauty, Chris! The Dash version is very rare. This one looks to be 1912-1914. The Junior Loc-Nob globe came later. The Jan-2-23 patent on this globe appears to have been a rush to production, where Dietz applied for the patent in September 1922 but actually did not receive the patent until 12-4-23, the date they put on the Fitzall. The January date on the Junior is a valid date that patents were issued, but no actual patent exists. So this globe appears to have been first produced in late 1922 in anticipation of the patent.
