Replacement latch part

I have owned my residence since 1972; the house was built in 1923. I have old-style outer gray aluminum storm and screen windows, with inner rope and pulley wood windows. A latch part on the lower right and left parts of my screens periodically breaks and needs to be replaced. I bought a small supply of pre-owned replacement parts in 1988 from a now-defunct local window products company. I just used my last replacement part today. I took four photos of my last part before I made my repair. Please see attachments. There are no stampings on the part or on the storm and screen units. Is this part something that you might have in your inventory? Thank you for your courtesies.
