Regarding pictures, I think we should be careful how to refer to them in discussion.
How about calling the pictures "original Ladder (Hindi)", "original Tree (Hindi)", original Ladder (English) " etc. Then we call can call "modified Ladder (Hindi)" "modified Tree (English)" etc. It is more labourious to type, unless anyone else has an easier way to be clear for comparisons made.
So I understand the following were done in the early 1960s :
"original Ladder (Hindi)"
"original Tree (Hindi)"
"original Trimurti (Hindi)" (which also has the Wheel)
"original Lakshmi Narayan (Hindi)"
And the following, as given by Brother pbkstinityshiva, were done in 19xx :
"original Ladder (English)"
"original Tree (English)"
"original Trimurti (English)"
"original Lakshmi Narayan (English)"
And the following, as mentioned by Brother Arjun, were done by BKs in the early 1980s :
"modified Ladder (English)"
"modified Tree (English)"
"modified Trimurti (English)"
"modified Lakshmi Narayan (English)"
So if you know of a further changed modified one, just refer it as "modified-modified Tree (English)". (It took us a while to be clear with the Murlis/Vanis versioning
) We're all extra effort-makers. Maybe bbysops can incorporate some sort of abbreviation.
