On my bearing, the whitish stuff you are referring to is a clear epoxy. It looks like Jim used a different material on yours. Inside that stuff is a brass(?) cup that holds the oil and sapphire thrust pad.
I really doubt any appreciable oil was lost by having the table upside down for 30 minutes. It likely just re-lubed the polymer sleeve. There should be enough oil in the well to last a lifetime. A drop or two on the shaft/sleeve once a year would be all you need. In fact, my bearing came dry and I added the oil, but after the modification, Jim shipped the bearing back in a small box with the well full. It was probably upside down and sideways for a long time in transit.
However, if you are ocd like me and most audio dudes, you can take a look by removing the two small screws underneath while keeping the bearing upright so as not to spill the oil. You can then fill the well if needed. On reassembly, be careful aligning the black o-ring that seals the well to the housing so it doesn't leak when tipped.
I don't know what kind of oil was used, but if you're in the U.S., I can send you mine. Jim gave me the smelly gear lube after installing the bronze sleeve and I have no use for the oil that came originally. PM me your address if you want it.

Can I ask a query regarding taking the bearing apart?, do you have to keep the bearing upright and remove the screws?, what happens then please?. Hopefully nothing will fall out when you remove the circular disc on the bottom?. Do you perhaps have the old manual which was supplied with the bearing please?. I thought perhaps that you turned the bearing over with the spindle pointing downwards to access. Any help appreciated and thanks to you for you much valued advice so far.
If you remove the screws without keeping it upright, the oil will run out. When the screws are removed, you'll be able to separate the upper part of the bearing from the bottom plate which is attached to the white stuff surrounding the oil well cup and thrust pad. Separating the two sections is the black o-ring I mentioned.
The only thing that you'll lose if not kept upright is the oil. Keeping it vertical is not difficult. If you were able to remove the bearing from the table, disassembling the bearing should be a piece of cake. There was no manual. Just an instruction sheet telling how to put oil in it. I don't have it any longer.
Thank you very much for your help on this appreciated very much I actually live in the U.K., if you wish to have a think about posting over here to me I'd pay postage all my best and thanks again
You're welcome.
I really think the oil is none critical. I would use a straight weight synthetic. Anderol 465 synthetic bearing oil is what Technics sold as bearing oil. Amsoil and Red Line make a straight weight synthetic as well.
Jim said he tested these bearings by running them at something like 300 rpm for 12 hours (don't remember exactly) with no oil at all and was unable to detect any wear.
