That kit probably goes back to the OF1000 days.

You should compare what is in the LR32 set you bought to the currently sold set.

The most important change is that the current sets include 2 each of the LR 32 Guide Rail Connectors. As a set of two the cat # is 496 938. Those serve two duties: with a single Holy rail they are the end stops; when two Holy rails are connected using ordinary connector bars, the LR 32 Connectors ensure the 32mm on center spacing of the holes.

By the way, the 2012 price for the set in a Sys T-1 was USA$ 465, You could check the 2013 price in a newer catalog or on-line. Unless I was absolutely sure the set purchased for USA$ 365 had all the bits and parts, I would not consider that a bargain. But your mileage might vary.

A very important consideration. Sorry I did not mention that, mostly because I only use OF1010 routers with my several LR32 sets.

Festool stopped using the FESTO logo long before the OF1400 was marketed, so for sure the subject LR 32 set mentioned by the OP is unlikely to be factory drilled for the OF1400.

Cross referencing with the 2013 catalog, looks like all of the parts are there. I will be using a 1010 with it so the hole patern doesn't matter too much, though I am assuming the holes be drilled if needed.

I'll have to take a closer look at the linear stops to see if they have changed. All three bits with the kit have no signs of wear or use.
