Research reveals the existence of only a handful of apples named "Birnapfel", i.e. pear apple:
1) The Minnesota horticulturist refers to a 'Summer Birn Apfel', described as: 'A white apple, rather small, very conic, with wrinkled skin. It seems not the same as Pear apple No. 267.' In addition, there are several 'pear apples' references.
2) there is a 'Birnapfel' in the Swiss gene bank obtained from Fructus. Genetic evaluations from Fructus have identified this apples as 'Mother'. See
3) The German Wikipedia refers to two distinct 'Birnapfel': 'Rigaer Birnapfel' and 'Revalscher Birnapfel' written up in Engelbrecht Deutschlands Apfelsorten (1889), See 
4) Der sichere Führer in der Obstkunde auf botanisch-pomologischem Wege Refers to yet another 'Birnapfel' in Switzerland: Schweizerschlotterapfel, also known as Schweitzer Birnapfel, medium size, shiny yellow-green background with dark red stripes, odorless, skin greacy when fully ripe, doesn't tolerate any pruning.
5) Proceedings of the Royal Horticultural Society refers to a 'Revalische Birnapfel': (of Russian origin) medium, short conic, pale yellowish green, streaked with rosy red. Table apple, second quality, ripens beginning August.
Chances are that the apple in Botner's list is 1) ans 5), both seem to describe the same apple.
