They have been modelled from NSWGR happy snaps.
We are supplying 4 set of buffer stops per pack.
The height is correct as per the photo’s and they lock in between the sleepers on peco code 100 flex track.
Easy to construct so i don’t think instructions are required.
Just paint them any colour you like and you’ll be able to stop your trains rolling off the end of track.
Please don’t say you dislike my paint job, i did it deliberately to show the locking tabs between the sleepers.
