I bought some "white" rubbers from an Aus supplier a couple of months ago and they were the same as you describe.
They didn't seem to happy when I asked for money back, probably the same company.
I got caught by that as well added them to an order I needed, couldn't be bothered asking for a refund, just threw them in the bin and cut my losses 
Me too. One time while Greg had "Gone Fishing" I brought some from an other Aussie supplier also and everyone was a various shade of yellow. Also brought some "new" globe holders all of which were rusted and some of which had solder on the lugs. To the suppliers credit they sent me some replacements but unfortunately they were all as bad as the original ones he sent. I ended up throwing it all out and waiting for the fish to stop biting. These days if RTBB doesn't have it I go overseas.
That's why I only use RTBB parts on my restorations (local suppliers).
Their rubbers have not been sitting on a shelf for 20 years and the parts are the genuine article. I've had a few machines in my workshop with LEDs that have caused havoc in the switch matrix after being installed. Revert back to standard globes or RTBB LEDs and the problem is solved. Price should not always be the governing factor in restoration parts. Quality is more important in my view.
100% with you there Nino. No point in paying half price for something that you end up throwing in the bin anyway. Besides I find RTBB prices are usually as good or better than most anyway and I've never had a quality or delivery problem with anything there either.
