using git to get a particular version of src

Hi,

I have this version installed:

13.0-CURRENT #0 2ed50808d2b-c254384(main): Thu Nov 12 10:03:35 UTC 2020

I'd like to get the sources for this (want to make a no-debug kernel) as I know 
this version works on this hardware. 

But -current has gone to 14 and what was -current is now 13-stable. What git 
incantation is required to get 2ed50808d2b-c254384 sources, given an empty 
/usr/src and git method of ssh://anongit_at_git.freebsd.org ?

thanks,
