First, do you have the original cap that was inside the IF can? The dot code should tell you its value. They are sometimes hard to read, but maybe we could help you out.
Second, I looked up other 1941 radios and found that the 41-295 listed the cap value inside the 1st IF can as 3000 pf (uuf). That radio has the same XXL mixer and 7B7 1st IF amp tubes shown in your 41-296, so it might use the same IF can assembly. Unfortunately, the crummy schematic I have for the 41-295 doesn't have a parts list, so I can't give you the part number of the IF can assembly.
Maybe someone else has better documentation than I have, so you could compare the part number on your set with the one on the 41-295. If they're the same, then 3000 pf is your value. If not, 3000 pf still might be a good guess.
For reference, the 42-355 also lists the 1st IF can cap value at 4000 pf. That IF can part number is 32-3794. The 42-355 uses a 7V7 for the 1st IF amp instead of the 7B7 in the 1941 radios.
