7 mm Galand

Just one quick Question today,
Did this " thick rim" cartridge ever have an internal primer like the early Perrin cartridge ?
I suspect there early ones with exposed primers were battery caps followed by the boxer primers , although that might just be to do with different manufactures. While I know the 9mm Galand was Patented in1868, I don’t know when his 7mm was introduced, but I believe they stopped manufacture around 1915.
Cheers in advance.

A quick look at this post, I did not see an IP Galand.

I finally had time to check a few other posts, but have not seen an IP 7mm Galand. Hopefully Aaron will say if he knows of any.
