Its most likely not an "old wheel" but the dealer aiming at a certain sector. "sector 4" or the 8 numbers right before the 00 is usually the casinos most popular target. 1,3,13,15,22,24,34,36. these are proven to be the least bet numbers (as a whole sector) in roulette so the casino has a huge incentive in aiming for and hitting this sector.
