I don't go inside these things. Actually, I get impatient and bad things can happen, so I leave this to others. I have heard that Howland's selective trigger was a way to get around Miller's patent and essentially it took something that was one piece in Miller is two pieces in the Howland.

The Non-Selective Single Trigger was introduced in the second 1932 Ithaca catalog at $6.50 and at the same time the price of the selective trigger (I'm guessing still from Miller) was upped from the $30 it had been since 1926 to $32.45.

The prices remained the same in the 1933 catalog.

By the 1934 catalog and price lists it appears to me the Selective Single Trigger became the Howland and the price dropped to $21.60 retail.

While the Non-Selective Single Trigger was $6.50 on an Ithaca, it was $4.60 on the 1932 Lefever poster, and on a Western was only $3.50 --
