@alsancle No, I don't think so, unless you mean the advertised h.p. of the same engine in 1930, but measuring at a higher r.p.m., 66. Interesting model...about 4th in sales overall, but an astounding 1st in survivability of all the 30+ models over 32 years. More than 50 6-61s are known to still be in existence. Partly due to numbers, partly due to near the end of production.
There was never a less expensive model than the "6-61", but some recent sales have brought top dollar; a "6-61" Sedan in Holland sold for 49,950 euros and a "6-61" Roadster in an Owls Head Museum auction sold for $57,200. The straight-8 Peerlesses should all be that high, IMO, depending on condition, and brass-era Peerlesses often are,
