What model are you after? The hinged one?

That’s a good question Jay, as I don’t exactly know which one should be on a Script May ‘42 GPW. If a hinged one is right for it then that’s good.

My april '42 GPW 17331 has a Ford badged Sprague filter with 2 bolt cover fitted from new, so that can be correct for you as well. Easier to find and cheaper than the Tobe with the hinged cover, I think.

Re: WTB Early 42 GPW Radio Filterette
The Sprague JX17 with Ford script tag would be correct, as Ford was phasing out the hinged Tobe 1107G at that time and the JX17 was beginning to be used in production. The friction cover type Tobe 1107G was also used for about 6 weeks during that time also, with stock of these units apparently depleted by June 1942. Remember, overlap of one brand of part with another was quite common in GPW production.
The Sprague JX17’s are more plentiful than the hinged and friction cover type Tobe 1107G’s so you might search for one of them. I bought a few NOS JX17 units a few years ago for my parts collection…here’s one of them. You can find these in take off condition if you’re willing to restore it…it would be much cheaper.

For those that haven’t seen the friction type cover Tobe 1107G I mentioned in the above post here it is…used for about a 6-week period between May and June 1942.

Re: WTB Early 42 GPW Radio Filterette
Just an FYI, the capacitors are 80 years old and could fail at any time resulting in a dead short and possible fire. They're just three foil and celephane coils and can break down over time. To me, that means that "working condition" with intent to actually use in service is a risk. I had a little trouble making the wires reach each other and still clear the cover, but I simply left the capacitors alone and used the box as a pass-through junction box. I connected each pair with 10-32 screws and Nylock nuts and flat washers with Penatrox (a conductive anti-sieze compound). I think the screws were 1/2" long, maybe 3/8", (so no threads protruded far enough to cut the the multiple layers of special electrical "rubber" insulating tape) topped with regualar electrical tape. Simply attaching the wire pairs to one of the capacitor terminals does not eliminate the risk of a dead short.
