Thanks Pyrtle, the eyecups look like they would last a lifetime, but just checking; if I find a good sample, lens, prisms, armor, mechanics, etc., and the eye-cups need to be replaced (if Leica were to have them), then it is an option.

I am thinking of obtaining one of these in either 10X42 or 8X42 and was wondering.
Do the eyecups unscrew for removal, if so, will Leica provide/sell any of these.

Andy,
Reference the title of your thread herein: "Leica BA or BN."
Are you talking about the recently made lower priced Trinovids or the old model Trinovid BAs and BNs?
As far as I can tell they don't come off my Original Leica 7x42 Trinovid BN. Nothing in the manual that came with it addresses the issue and I haven't tried to unscrew them.

Andy,While searching I stumbled on this archived Trinovid (40009) made from 2012-2015?, not sure, but it appears to be a very well built glass and using it under gray/ rainy cloudy conditions it performed very well.
Yes, an anti clockwise turn on the eyecup when raised, would start the unscrewing process. The engineer's used to lubricate with a PTFE type grease. Best to leave well alone I feel, but useful to know I hope.
Richard, thanks for the photo, these were the range I was referring to. The whole of the push up / down eyecup can be unscrewed.
I'm really surprised that this is a revelation to some. I worked for an optics retailer from 2002 throughout to 2010. We routinely used to hold a stock of 32mm and 42mm complete eyecups and changed or sold them as required.
My own 8x32BN and 10x42BA used to benefit from the occasional removal, blow out and very gentle clean of the eyecup, they could trap grains of sand.
From memory the little users booklet also described how to do this as well as set the focus wheel diopter.
There used to be a member on here who was a Leica UK service engineer based at Milton Keynes who could probably confirm this. He wrote a little book on the previous model Trinovids ( rubber fold down eyecups ) before he moved onto Carl Zeiss UK as their service technician. I think he moved to Norfolk and still repairs/services these types of optics and probably older models.
