New project: Ithaca crass model

[alcaviglia]

Bach, the parts you are referring to comprise the trip assembly. That is what keeps the toplever to the right and the locking bolt in its rear position until the locking lug on the barrel set trips out the pin upon closing the breech.

Apparently, the trip spring (leaf spring) on a Crass model is a bit longer than that found on a Lewis model, and what Numrich had listed under its Crass model parts for sale was a Lewis model spring. It makes sense, the longer spring for the Crass model, since I believe the Crass receiver to be a bit longer than the Lewis.

If Jeff can get you the overall length of his Crass model spring, you can attempt to contact Numrich. Hopefully they will be willing to go through their stock of "Crass model" trip springs looking for the longer one(s) to send to you as a replacement. As mentioned once before in this thread, I had given something like that a try with them before, to no avail. Probably worth a shot, though.

In the first picture the trigger guard was turned to the left. Your seeing the curved part of the trigger guard behind the second trigger. Here it is in its proper position and also swung to the right.

gotcha, thanks!

I have never rotated my trigger guard, so that's why it looked off to me...

thanks, Robert!

any chances you have any more photos of your Crass you can post and share, particularly taken apart to any degree?

can you please elaborate exactly how that functions?

without that trip assembly part, I can visualize how the spring keeps rearward pressure on the barrel locking bolt (via the trip assembly pin located in the forward notch of the barrel locking bolt), but what I cannot visualize is how/where the locking lug on the barrel set trips out the pin (which pin?) upon closing the breech...?

I'm sure having that part would help...

The locking lug on the barrel set strikes the trip spring directly, moving the trip pin out of the trip hole in the locking bolt so the bolt shoots forward locking the barrels.
