Can you help me with wood storm windows

A quick learner from Ann Arbor MI says:
We are installing wood storm windows on storm hangers and would like to be able to tilt them out for ventilation.

Storm sash adjusters have been recommended (e.g. Stanley), however it is my understanding that they mount on the exterior stop and our storms will be 1 3/8" thick and will have a rabet to fit around the exterior stop so the face of the storms will be flush with 5/4 window trim.

It is my understanding that most storm sash adjusters mount on the exterior stop and thus it is a problem if the wood storms are 1 3/8".

Is there a type of sash adjuster that mounts to the window sill or some way to modify the mount so that it will work with our application? Or, is there an awning window adjuster that will work and if so, can the storm hang on storm hangers (if so, what type) or are hinges needed?

Any other suggestions would be appreciated.

Hmmm... you might want to start out by looking at our 20-018. This serves a function similar to what you're looking for. Check it out and let me know what you think.
A quick learner from Ann Arbor says:
Yes, the 20-018 serves the same function. Is it also intended to mount on the exterior stop? If so, there will be the same problem with the 1 3/8" thick storm sashes because 1/4" of the storm sash will be rabbeted so the face of the storm is flush to 5/4" trim. Do you have a solution?

The 20-018 mounts on the inside of the sash. Unfortunately, we do not have anything that is installed on the outside. I remember a customer very recently who had a similar push bar that mountain on the outside. It was very, very old and we do not believe it was made anymore.
