Boys antitank rifle mount for T-16

[Bert Sobers]

I am searching for information on the type of mount used for the MK 1 Boys Antitank Rifle on the T-16. I have seen photos of it located in the lower port on the left front side of the vehicle but detailed information on the type of mount has not been found. I suspect that it was not "hard" mounted in a fixed pintle but used some type of recoil absorbing mechanism in addition to the internal buffer in the weapon. Thank you.
