Which compressor head

I bought a horizontal version 30 gallon crapsman oilless that was dead, I have a 5 hp briggs powered compressor, was on a set of hot dog tanks that sprung pinholes so I cut the engine mount base off of those and welded it to the formerly oilless powered tank, been using that as my backup or for if I need air on the road for probably 10 years like this. My son has it at his house currently, until he can find a 2 stage upright like mine for his garage
