Cannot find this lego piece from 50s - 70s era anywhere.

Hello everyone! I am currently going through old lego from my dad and found a lot of 50s or 60s lego. I found an arch piece that looks like an old lego piece, but I am unable to find it on bricklink or rebrickable. No idea if this piece is in the LDraw library though. This arch piece is a 2 x 2 x 8 and hollow. I have stacked two old bricks to confirm the height just in case. Does anybody know if this is a real lego piece or not? I have pictures comparing an old 2 x 8 hollow piece with the arch piece next to it. I asked my dad if he knows if the piece is from lego. He does not know for sure, because he was too young and does not remember.



The studs look really similar on this picture, but the arch looks like to have a more clearer print. The print does exist on the 2 x 8 piece, but more subtle. On rebrickable some pieces do have a more clearer print on the stud like the arch. This made me interested in looking this piece up.



The arch looks somewhat different from existing arches on bricklink and rebrickable. No idea if this would mean anything, but this piece has a higher arch gap than newer arch pieces.



The hollow side of the piece is more interesting to me. I have put a second arch piece next to it as well, because the hollow side looks a bit different.

Does anybody know how to verify this piece and if this is lego? Please let me know if you want more pictures of this piece if necessary.
