Despite the success of the standard scale props, we received many requests for the distinctive round-blade, pointed boss designs of the 30’s and 40’s warships. This range has therefore developed in parallel with the standard types and is now available in most of the same sizes. Three blades only, left and right hand in all sizes.
The typical thread types for these props are M2 (for very small props), M3, M4 and M5. You can specify another thread type if you know exactly what you need.
Reference numbers for this range give the diameter in inches followed by the pitch in inches. Eg. 1415 is 1.4" dia. x 1.5" pitch. There are a few anomalies: 0708 is 0.7" x 0.8", 0751 is 0.75" x 1" and 0871 is 0.87" x 1"
