In regards to the blade carrier patent,I have at least one carrier with the Ramps/deflectors still mostly intact and a few with just the outline.

Can you please answer these questions,

What was the first blade Carrier Victa used on a production mower (Disc style) as the Patent example carrier may be Victas first designed disc blade carrier, but is not the First Carrier fitted to a Victa Rotary.

Does the carrier with the ramps" and without share the same pt no?
And What was the title/pt no of the ramped carrier in the patent?

And also the Pt no for Victas First Disc carrier, fitted to the early Model 1 rotomo, which differs from that of the Patent.

From the date of the patent submission (May 55) of the new Ramped" carrier, how long until it was approved and put into production, and what model was it first used on?

Do you have any documentation on when the 9C plate was released, and on what model

And also confirmation on the 9B plate being used from 1955-1960 and what models did it cover.

Thank you.

Also the plate in the first Image is more than likely generic as youve said, as both mine were fitted to HG Palmer Dep store Models:)
