Hello,

We can't be sure without knowing your exact measurements but you can start by comparing the specifications of the 91-176 to yours. If you notice any discrepancies, let us know and we can go from there. Thank you!

A professional from Beaver Bay Minnesota says:
Hi again the thumb side of your corner latch 91-176 sticks up above the main body of the latch by the corner bracket. Where the one I need is straight across and fits in side of the body. The one you have wont work because the thumb part will be in the way so the corner key wont fit in its track its a separate track from the main body. The corner key on the one I need is 3/16 x 3/16. Thanks!

Unfortunately, I don't believe your Gerkins latch is still available. The only one we carry similar to yours would be the 91-176. If you don't believe that it could be adapted to work for your storm sash, you may want to check with a hardware store in your area to see if they have any old stock of this particular part.
