Chargers for power tools 18V & 14.4V (Calcutt HG5)

Hi. I have some power tools to donate to a local Men's Shed but the chargers are missing and I'm wondering if anyone has some spare.
One is for Bosch 18v batteries with the semi-oval shaped stem and the other is for 'workzone' 14.4v ones. Please see the pictures.
I'm pretty sure that these are fairly generic shapes so the chargers don't need to be branded
The bosch batteries are marked as T in the top terminal, C in centre right, -ve in bottom left and +ve in bottom right.
The workzone one is +ve, BS, TV (no contacts in this bit) & -ve reading from left to right.

Many thanks
