Holt radiator help

Has anyone ever seen this kind of radiator used before? I’ve looked at various t35 holts that also have the radiator exposed (no front guard) but they all look like a normal radiator core. Was this an early radiator repair shop job or was this a legit option? If so, was there supposed to be a screen to keep bugs and debris anway? All my 2 ton parts books don’t go back far enough to show holt t35s.  [attachment=76949]IMG_9194.jpeg[/attachment][attachment=76950]IMG_9192.jpeg[/attachment][attachment=76951]IMG_9229.jpeg[/attachment][attachment=76952]IMG_9228.jpeg[/attachment][attachment=76953]IMG_9218.jpeg[/attachment][attachment=76954]IMG_9223.jpeg[/attachment]

Nice looking 2 ton. I’m going to keep the radiator as is then. I didn’t know if it was wrong and I’d need a core made up, but I like the look of the tubes.
