Well, not really the same; actually quite a bit more complicated than the later sets. Bushings and washers everywhere...

These were used on the early Victa type 9B blade carrier disc, that was fitted to the 1955-60 18" models; the Rotomo's through the Model 5. This used P/No 9-024 blades, very similar to 9-150's but with a smaller hole.

Quite rare these days, as most were replaced in service by the later type 9C carrier, that used the then current P/No 9-150 blades and P/No 9-164 shouldered boltset.

How the assembly went together:

The 9B carrier:

The blade mounting bosses were brazed into the carrier, and as can be seen in that pic, were very subject to adjacent cracking. They also had an Oilite type sintered bronze bush pressed into them. So each blade mount had, aside from the bolt and nut, two bushings and six assorted washers.

Even back in the 70's, if a mower came in for service with the old setup, it was way cheaper for the customer to just change out the carrier, than to muck around with all the old bits. Victa supplied the 9C carrier ready-fitted with blades back then, for just this swap.
