Vintage s&w shoulder holster info

[chev37s]

I have a vintage s&w shoulder holster that is marked with the numbers (43) (36). I have searched and found similar ones but not this number and was wanting to know if anyone knows what guns it fits and barrel lengths.

36 is the size code for 6” K frame revolvers. 43 is the holster model number. 6” K frame revolvers should fit, with or without target sights.
