Hello grumpy ,
first of all let me say I'm pleased to see we may differ in opinion in a civilized matter - I've seen very differently in my time discussing these insignia .
That being said , I do believe there are differences that can be made out , they are very subtle indeed - but consistent .
Here's a picture from Traders of the lost surplus where these repro's were on offer ( $ 7.50 ), unfortunately I have not been able to secure one for research purposes , but do have dozens of pics of THIS type alone , taken from various discussions ( always deemed to be bad ) - and own an original of the type it mimmicks .
It is No. 2043H from picture shown , the other 2 are more easily identified ..
