We are in the process of refurbing several GR instruments, especially
1311a's. Several are missing the 5/8 inch diameter hemispherical plastic pilot light threaded lens caps.Newark sells these for a mere $320 plus shipping on four month nonrefundable delivery, but they may be the wrong size.
Any sane sources on this item, new or used? Color not critical, white preferred.

Sound like they need to build a mold to make them.
How about making one with 3D printer?

Hello,
well, if the surface quality of the parts from the 3D printer is sufficient. The voxel size might be a problem at the thread.

For $320/per, I'm tempted to offer the same deal and make them by hand!

Like Tim said, you can always fix/polish it by hand. 3D printing should give the base frame to work on. Perhaps, they are doing it for $320 each.
Actually the best way to do this for a handful of them is probably to make a mold out of aluminum or brass ('cause it's easy to machine), cast them out of optically clear epoxy ('cause you can do it at room temperature by hand), then thread each one as a post-molding process.
About the only special piece of equipment you should need would be a vacuum pump to pull the bubbles out of the mix before you cast the parts.

-- Newark sells some 5/8" diameter domes: http://www.newark.com/catalog_130/index.html?page=1360 There's no thread size information from them or from Ozram-Sylvania, but there's a contact page: https://www.sylvania.com/en-us/about/Pages/contact-us.aspx
I probably have 2 or 3 buried somewhere. However, if you want to pick an choose, do an image search for "5/8 pilot light lens". The first few look like they'll lead to a better source of parts such as:

Suggest the cheapest source is to buy old Heathkit oscilloscopes. Unscrew the oscilloscope from the pilot light lens and discard.

Perhaps this would work for you? It has a metal threaded part, and the listing doesn't give the sizee. A phone call or email might get more info.

I know a place that may have one or two large boxes of complete lamp socket assemblies and possibly a bag of lenses. They are removed from equipment
being retrofitted, and might be available or cheap. They are mostly red and amber, perhaps a few green and white.
Or you can order single pieces rom Allied for $0.39 each, any color you want except black:
