All I have is the 55-27" tanks. I typically go to the welding supply company but if they are closed, I go to TSC. Both places are tank exchange with no questions asked.
I maybe incorrect, but I am pretty sure all pressures for the same gases are the same, so if your buying O2 in 2 different size bottles, and getting different pressures then somebody MIGHT be transfilling them and shorting you on xx number of cubic feet of gas,which is how bottled gas is typically sold. Different gases (high pressure) fill the same size tank at different pressures to reach the correct cubic footage for a bottle.
Clear as mud!!!
