Air tank sizes
It’s got a motor? What’s the rating on that?
And the pulley size?
Looks like the sheave is around 9 inches – bore about two and stroke maybe three?
All that in aid of guesstimating the flow to answer the tank question.
Good with the ruler though. Just kinda hard to see.

It is definitely older than mine. I have one I can not completely identify. Just found a picture of a Ingersoll Rand 30P30 which has the same casting and filter plate design however mine has four cylinders and the 30P30 has two. It stopped building air last year so I had to cut my own gaskets for one of the heads. It keeps on pumping though.
I have a Model A, (no other defining marks on the compressor body). its connected to a 62l upright tank and is ran from a single phase 240v electric motor. i aquired it from a family friend after they downsized their property, here in the UK. It has recently started to weep oil from around the fill plug and the crankshaft seal. i am looking to find a rebuild kit for it (but have resided to the fact i may have to source seals and make my own gaskets)… i am also unsure of what oil i should use on… Read more »

Hi ive just bought this Ingersoll-Rand compressor. Its a stainless tank with wormald company engraved in it. I assume a after market tank? The motor looks re built by paint work. Its a General Electric and says 3/4 HP on motor(pics attached). ID Plate on comp itself says Model No. 2 Serial No. 02157 (engraved but a 1 printed before this number and a B Printed after it) and Max Pressure 862kpa(pics attached) any idea of its rareness, age or price or what it was built for would be much appreciated. Thanks
