Impatiens …???
Since it is from old collections the quality of image is not so good.

Pl. check comparative images at /species/a—l/b/balsaminaceae/impatiens

Could not get any match !

Unfortunately not I. drepanophora
I. drepanophora is one of Impatiens with upcurved spur (curved over lower sepal, towards upper petal).
Your plant has apparently downcurved spur.

Any idea … ? Any closeness to Impatiens vidyae R.C.Srivast. ?

I think looks different (though close) from Impatiens vidyae

Friend suggested Impatiens leptocarpa Hook.f. !
Please advise!

Yes it is I. leptoceras DC
