C-Mech storm door handle

Hi,
My home was built in the 2003/2004 time frame. We bought the house in 2009. The storm door itself is still in excellent condition, however, recently the latch release handle on the inside broke off in my wife's hands.

I am unable to source a replacement part locally. The inside of the castings say C-Mech.
I am inserting some pictures to help clarify exactly what I need.

The rest of your handle appears to be in good condition too, other than the broken inside latch. Could you get away with just replacing that? Check out our 40-150, I think this would work well for you. If you want the whole handle set, we won't be able to provide an exact match but I believe our 40-058 can work as an applicable substitute.
