Service Bulletin No.820

I have this fantastic old compressor that I am wanting to bring back to working order.I even have the original Service Bulletin No.820 that contains all the part #'s as well as a blowup image of its internals including a maintainance and use section.
The problem is so far I have not been able to locate any parts provider and seems the places I have made contact with could give two hoots on lending any possible sources they may be aware of (what happened to customer service)!!!
To get this thing going at the very least I need the Diaphram Part no. NCD-11 and a Rod-Connector Part No. NCD-21 (Looks like a piston rod). I know it works and even with the cracked dry rotted Diaphram it did ok.Of course stupid me tried to fabricate one out of an old inner tube which worked but it was too thick and the added pressure caused the rod to crack....bummer! I believe the rod is pot metal and i am not sure if it can maybe be welded or even glued with the correct type of glue....any advice on that would be super!
Please if anyone can help I would be grateul.

Thankyou very much,

P.S. If anyone on this website has a need for the Bulletin No.820 provide me with your address and I will be more than happy to make a copy and send it to you.

I have one that my dad got off of a painter friend of his he was going to lessen to paint with it but he didn't get a chance to do so I'm 55 years old he got it when I was right around 10 years old every once in a while he'd use it to blow up bike tires anyhow the thing has overspray all over it but it purrs and generates about 30 to 35 psi if your interested email (Contact information has been removed, to ensure that all responses will be available to all visitors on this forum.

Hi Frank

Henry here from the Niagara, Ontario region.

I've been trying to find maintenance info for my model Devilbiss P NCD 501 air compressor and stumbled upon your post.

Would it be possible to get a copy of your Bulletin No. 820?

Hope you've had luck locating/fabricating parts for your's.
