Was Winchester the only maker of the 4 row 19 hole heat shield variation?

My online reading indicates that this was a mid war variation for the 97 then the M12?

Were there any other trench gun manufacturers that used this 4/19 style of heat shield?

Has anyone repro'd the 4/19 before Taylor? they seem to be the only repro that I can find for it past or present.

Thank you!
