Hello,
I have a full version of the Bowdwitch on computer files pdf types. 
About 40 files and some of them are 1300 kb.
Also, I developped a navigational computer program in Excel VBA : 
astronomical / navigation etc...). The astronomical has a developped 
almanach and the almanach is valid for at least 50 years.
If you are interrested to receive the Bowdich or the program, please 
give me your full email address.
For the Bowdich, as the files are quiet large, I must send at least 20 
email to avoid the saturation.
Everything is free of charge.

Best rgds
