Similar to your 26-129 but not quite the same. Overall length: 3 3/4 inch. Main body: 11/16 x 1 19/32 . Nose: 1/4 x 3/8. Tail: 1/4 x 1 25/32. Thickness: 7/32. No brand or number on pivot bar. Aluminum frame of sealed glass stamped as ALWCO-84. Same vinyl pieces inside the four corners of vinyl window frame is used to hold the pivot bars and spring loaded latch.
Any suggestions much appreciated.
Thanks
