GurfatehBro Bulleshah Ji,
The picture of Bhagat Singh as given below was also with Mandinder Jeet Singh bitta of Anti Terrostst Front and he had as claimed to be real one.
can you see the the chains in the hand of Bhagat Singh Ji,
As per Bitta these are the photos of him taken in jail and that also was told that he was jailed only after bombing assembly.At that time he was likke the way you want him to be.
But at his end as his last photo is one which is attached by das.
So he went into jail without hairs but in jail he grew that up.
In fact mnay terrosists or freedom figherts whichever you call them in Kahlistan movment also did change the face for covert operations.

In das's depratment many Sikhs may have to change the face,Das even had to wear helmet once.

but unlike in hindus when once say eaten beef,always outcaste(say father of das keeps utensiles separte for das).
but here we have mechanism of Tankha ie reconversion and sometime pardoning by faith.
It is what Svatrana Veer Sarkar conceptulsied in his book Gomantak.
anyway in orrisa still we ahve that reconverts from chrisitnaity to Hindusim as per thier Shankracharyas are not allowed in Commone Hindu Temple but ,speacial Swastik Temples are to be made for them.
Yuo could see that in Harmandir Sahib ,we have had white Ragi Chris Mony Singh.but we can not have negro Brahmin in Jagganth Temple.
This is insptire of the fact that we have whole procedure to make a neggro Brahmin by Jagyopweet Sanskara as meanioned in various Samritis or Brahman Granthas.
Das was disccusing this with Brother Balbeerr Singh Ji,that in Gurmat both Ygyopweet and Cicumsention are not discouraged but,what is encouraged is to understand their meanings.
Forgive das if das ever un intenetonaly offended you.Das is at oyu side as in gurmatwe do not have concept of good or evil and all is good as God is in all.
