Window latch

I have looked at the dimension on these parts and it seems that they would match with 26-244, 26-243 and 26-408.
Pictures are as follows:
pat 5139291 10H = Top view broken piece may correspond 26-243 or 244
pat 5139291 10H-2 = bottom view broken piece may correspond to 26-243 or 244
pat 5139291 = part in situ may be 26-244
8590-1 = bottom view may correspond to 26-408
8590-2 = Top view may correspond to 26-408
Could you please verify/confirm that these are the correct parts.
Thank you.
