Dear Steven
That would be fine.  We will call it M(2)56FH in future.
In addition, this is the same Minute used in our earlier papers (listed below), where we sometimes labelled it "M56i", which is how it had seemed to us to be labelled by the Hiromi lab.  Since the label was handwritten this probably represents a misreading by us or misspelling by them.

Hi Nick,
Thanks for the info about your M(2)56F stock.
I think it would be good to give the stock you use and got from Hiromi a specific symbol - then at least we can associate its specific and known usage in Li & Baker 2007 (FBrf0201270), Li et al 2009 (FBrf0209362), Kale et al 2015 (FBrf0228860) and Kale et al 2018 (FBrf0237712). How about calling it M(2)56FH (after Hiromi)? 
Let me know if this sounds OK.
Cheers
Steven.

Dear Steven
My recollection is that I obtained the FRT42 M(2)56f stock from Yash Hiromi nearly 20 years ago, but I do not seem to find this mutant listed in any of his publications.  Yash no longer has a lab and unfortunately I don't know where he got the mutant so I cannot say whether it corresponds to any of the known alleles.
sincerely
Nick Baker

Hi Nick
In your paper, "Ribosomal Protein S12e Has a Distinct Function in Cell Competition" (FBrf0237712), the Methods section says "RpS18 mutation M(2R)56f Laboratory of Y. Hiromi".
Do we know if this M(2)56F mutation corresponds to any of the named mutants here:
