Picked these up from an estate sale. $150. 50gpm flow guage and a smaller one, bunch of pressure gauges, hoses, adapters, etc. All in a metal old school toolbox. Guy was a heavy equipment mechanic and the family was happy to see it going to someone that can use it. Hopefully will come in handy. I know the flow gauges are pricey.
More Couple guages are broken or unreadable, but most are good.
Nice score. You did very well on that one.
