Looking for this font from a shirt design seen on a custom apparel website (B Unlimited)

I'm just looking for the font for 1870. It might be the same font as the KAPPA KAPPA GAMMA text below, I'm not sure. If someone identifies either, please let me know!

 

Here's the link that the image came from: https://www.b-unlimited.com/products/ft2018-046-fall-template

 

It's just an example of a custom design that this custom apparel company can print. The design was likely made on a computer and then screen printed onto the shirt. Not sure when the font would've been made, but the design was published recently if that helps. 

 

Looking for a digital version. Commercial fonts are fine. If there is a free alternative, that's nice, but it's not a must. Just want to know. Might want to design something else with this font.
