Two of my favorite toys , a fat 8x60 and a set of blc 7x50 gas mask.
Although it is not popular I have had both cleaned professionally cleaned , my take on this is that I use both sets and want to get the best from them.
In their working life they were never designed to last 70 odd years without any maintance or internal care and as time goes on these old ladies become vunerable and I just think they should be cared for in respect of prisms and glass surfaces - lubricants were never desgined to last for 70 years and as they degrade they damage the sets.
It is highly unlikelyt that they will need attention in my life time and I pass them on to the next generation of collectors in good condition.
Repainting I don't do - it cvhanges the character of the sets compleltely and it is not for me.
The benutzer on the fat is a reproduction as is the rubber cord .
