Got a gift from a Neighbor, Need some Help

So i bought a BT65 a month or so ago and have been trying to save for a Yong Heng compressor to fill the gun, well about a week ago an older guy from across the road came over and i showed him it and let him shoot, he liked it, anyways we get talking about it and i say i just need to get a pump to be able to shoot more... Well it turns out that he did SCBA instruction in the 60's and had a old pump... Well a week go's buy and he showed up today with it, picture bellow. Its a ~1955 Cornelius Model 130R1500, 110V and 3000PSI! He says that it needs some cleaning but works, he got 1000PSI before turning it off and bringing it to me, he gave it to me and said Marry Christmas! I have just started looking into it but it seems like it will do the job for me, I just want to fill my gun to shoot and i don't need to go over 200BAR so i should be good!

From looking at information on it, i need to get a relief valve from somewhere and the hoses, i have to check the filter too... hope i can find a good one....

Anyone have info on this compressor? Also does anyone know where i can get the valve and hoses i need, plus anything else i may need, I am new to this....

** I NEED SOME HELP PLEASE... So i guess from the manual i need a relief valve for letting pressure out of the line, i can't seem to find one.... I am ordering a tube-style filter (https://www.aliexpress.com/item/PCP-oil-water-separator-30-mpa-4500psi-310bar/32815274871.html) and another hose (https://www.aliexpress.com/item/High-Pressure-Hose-64Mpa-9000PSI-W-8mm-Quick-Connector-for-PCP-Automobile-Auto-hand-Pump-Airsoft/32757954434.html)

It will go from the pump to the filter, then from the filter to the fill adapter... Somewhere i need a way to depressurize the hose... I can't seem to find anything for this...
 
Ok so i am trying to work out what i need by myself as i haven't heard from http://www.sheldensportinggoods.com/ yet, and there is little to no info about this pump out there....

So here is my current parts list, i think this would be everything to get to using it....

Going from the 1/4 NPT port on the pump to a 1/4 NPT (Male) to 1/8 NPT (Female) adapter, then from the 1/8 NPT port to a 1/8 NPT (Male) to M10x1 (Female) adapter, Then from there i go with a M10x1 Hose to the filter and then from the filter to the guns probe... 

I think i got all the parts i will need, i made sure find to get Stainless steel as most i saw on eBay are brass...

I will do some more looking before ordering, got to make sure im right.

What i am looking at;


There is a filter(?) on the pump (has the gauge, relief valve, and the water/oil drain plug) I am just going to leave it as it is i think and use the external filter... I pulled the drain plug on it just to see and there was some black beads on the end of the bolt, maybe some of whatever filter was in there?
