SWISCO - The Replacement Hardware Authority

Old 1970s aluminum windows

A handy person from New York says:
I hadn't planned on sending these pictures to you & only took them to come home and "order" the parts myself but now I am thoroughly confused. We are replacing these for a client who should really be replacing the whole window but the house is in contract to sell and this was a sticking point after inspecton...windows that slide...We need 4 for the LR windows of the same size 23 inches marked 2240...2 of the 17 inch marked 1620 (?) and 2 of the 17 inch marked 1610(?)

These numbers were given to me by my dad who had the parts in his hands & I was writing this down & took the photos so I could come home and order them...Do you have enough info for me to order from?? I did not see one clip in any of the windows & am not really surprised as this apt was a cash cow being used for a rental for years...things were not fixed properly just made to work with spit & bubble gum. Hopefully you can help me...the deal is in limbo until these small issues are addressed....
