The cylinders with the flattened sides in the photo with the railway track are Palmer Bros. Model RW. The 1921 date for the photos would confirm that. The RW came on stream as my best guess about 1920 so why would they be painting the cylinders in 1921. Why are the long studs sticking out of the cylinder on the left? Perhaps to permit leaning the cylinders over while painting the under side of the valve chambers. The RW went out of production about 1927. The ZR of 1925 finished off the RW, NL and NR by 1929. The five spoke flywheel looks like a M/B what is it? |

Wonderful photos Richard!
Notice that they were taken by the famous yachting photographer Morris Rosenfeld. His collection is now at the Mystic Seaport Museum in CT.
See this bio on a navy history website. |

I only noticed after I sent my previous comment that instead of a 1"NPT lower water jacket drain these cylinders have an SAE style flange. Strange I have never seen the flange style in that location on any of the NL, NR, RA, RW, ZR PNR cylinders. Curious now to try and find a catalog or other engine that shows that style. Many makers by 1910 had switched to SAE style flanges for water, intake and exhaust connections to avoid the damage trying to remove a rusted fitting from a cylinder. I wonder why Palmer would have gone back to NPT in the later years??? |
