I don't have a price or part number from WGP and suspect they didn't go into details as Irv may have replied after normal business hours last night stating only that they had a minimum order and would reopen for business Tuesday after the long weekend. Brownells lists a part with a similar description as $5.95 but of course won't ship gun parts to Canada.
Here is apicture of the fully functional one on the 1922 trombone::

and the broken one on the rifle I got back from bluing in BC. (not supposed to be blued so maybe the heat or bluing formula made the spring brittle so it broke on reassembly).
