It was a sad day when Airflo had to stop constant rail production because David went off to college, but it seems after ca half a year of that there's a big change.
David from Airflo is now renting a garage where he lives, and moving the shop from his home to there! This means Airflo as of like a week's time is going back in business, with rails always available and all the goodness we've missed coming back. If you need a rail Airflo really are the way to go!
