Maybe I can clearify
First there was a part 142.dat - Plant Flower Stem
Then the right name was found 3741.dat. So 142.dat is now a "~Moved to" file with reference to 3741.dat.
Then we discovered the correct shape of that part with different angles for the flower bars.
If we make just a "~Moved to" or simply adjust the shape all flowers in all models in the world are not in place.
So we decided to create a 3741a.dat and just tell the user that 3741.dat is obsolate.
This has been done for backwards compatibility.
I hope I remember all things correctly
