You can just rename .blend1 files to .blend and work with them in Blender normally. This is because .blend(number) files are just backups done automatically so users can revert the changes and do not lose the data in each step. It appears that this backup function was in Blender as far as 2003 and maybe earlier.

Convert from blend1 file
to blend file
The tables with software actions are a good pointer for what a certain program does with various file types and often may give users a good hint how to perform certain file conversion, for example the above-mentioned blend1 to blend. However, it is not perfect and sometimes can show results which are not really usable because of how certain programs work with files and the possible conversion is thus actually not possible at all.
