I have several that size and they all came off mainly 250's and maybe a 125 or two. From what ive seen all the different brands uses the same supplier who was making these and each company stuck their own sticker on them eg DG, Answer, Roost Factory. I have DG and RF ones etc and they all look identical, so there must of been some guy in california welding these together all day.The bottles are all the same size for different capacities from what ive seen and the differences are mainly the placement of the outlet pipe and some were shaped differently to fit the available space under the tank. I have one off a KDX and it is really long and skinny, probably because they couldnt fit the standard size one in the above photo so they achieve the same volume by having it longer and skinnier.
