No. Eck Dynamo it appears started using the Irving propeller reissued 15 patent(---ming blade) on their motor tags after the 17/18 --ming blade models were on the market.

I have no clue how long Eck Dynamo had those --ming blade models on the market.  In the full read electrical trade books up to 1922 there is no mention of the --ming blade being taken off the market.

Are there any 12" --ming blade models with STEEL SPOT WELD GUARDS I am not aware of?
