You can find these on eBay, just do a search for: magnifiers.

Rick, I just picked up the exact same magnifier from Amazon and it's awesome! You can see micro cracking as clear as day. Only tricky part is taking a photo through that loupe.

 

Here is an example of my original MP helmet magnified as a model for what to look for

Another example, paint looks pretty smooth from a distance but, under magnification, it's got micro cracking.

Hello

 

Very interesting thread...

 

I agree with the high % of  age cracking when paint is vintage

 

I have noticed that is more present and noticeable in white paints. Others does not crack so evident

 

Here you have the visible age cracking in the white paint but not so noticeable in the red paint on this medical helmet where cracking seems to be caused by the white pain coat t under the red one

 

Have also a 90th Div with similar evidences.

I believe that's because vintage white paint contains lead carbonate which, over time, produces those distinct geometric cracking patterns. When exposed to the elements, lead carbonate oxidizes over time and forms that yellow color you see on old white paint.

 

Other factors to take into consideration for cracking is that some paints just don't adhere to each other and crack/flake easily afterwards.

 

Here's a pretty cool WWII pic of a US medic white cracking paint on his helmet, it was already a problem back in those days

Not just helmets..magnified lighted loupes are useful for ALL sorts of things..a solid and wise thing to have in my humble opinion..
