I need to replace the right and left Truth operators, which are 10-inch straight-arm. The operator is stamped 45261 and marked "XX202003 1029" where "XX" are two smudged digits I can't make out. The two-bar jointed slider, which I don't need, is marked Truth 30818 and is stamped "PRY TO REMOVE SASH". They operate the 55"W x 50"H Patriot (now PlyGem)kitchen casement window pictured, which was installed by the builder in 2003.
I understand that the current version of this operator has a rounded rather than squared-off gear box cover. That is OK. I need only the operators and handles; the rest of the hardware is still OK.
The attached photos are self-explanatory.
Thank you.
