Quite naturally, I forgot to take the phone with me and hence do not have a picture yet. Here is one off the web which looks the same but for the number of kits.
Gertrude had 6 kits on May 1st. 5 are black and 1 looks surprisingly white (hairless and pink at the moment).
Mable has developed her 2nd chin and has begun making her nest.
I expect the 2 deliveries to be fairly close as Gertrude delivered on the last day of her 'expected' due dates.
Hopefully Mable's delivery will be faster in case I need to (unlikely, but...) move some of her kits over to Gertrude in the event that she has a large litter. This fostering is only possible if the deliveries are within a few days of each other.
I did pick each one up today ( 24 hours after birth) to accustom them to the feel of human hands, one is larger than the rest and one is far smaller than the rest.
If the pink one does indeed prove to be white -- and female, she will become the new Mable.
