Not exactly, no. Ro85 and Ro87 (Pica and Elite Cubic) are very close to OP's type sample but the W's have sloped sides and the numerals are different. It's not a copy of Sentorial either, the most apparent differences are the Capital Q and K. I could not find Ro83 in any of my catalogs either, it's a bit weird. I've seen RaRo slugs on Olympias before, it's possible this was something they only did for them.
