Of course!
Photo Hall was a large Parisian Retailer, who also had his own branded versions of camera sets, lenses etc!
Their products are very common on eBay.fr.
I have their comprehensive catalogue from may 1912 It does refer to your Aplanat as the “budget” lens version on their camera sets, but they push the anastigmat alternative.
I enclose the catalogue and the order slip which was loose in the catalogue. They no longer exist so the address/telephone/telegraph address will not respond.
