Picture shows what I have, except mine is made by Gaspro for use with acetylene gas. Mine is almost entirely brass, except for the lenses and dials for the gauges. Mine is also in EXCELLENT condition, practically new. The left gauge measures PSI from 0-30 with 15-30 being in the red warning area. The right gauge measures PSI from 0-400 with no red warning areas. Click on the "more ads by this user" button to see what else I'm selling. Thanks.
