If you want something fun to chase, try circuit board WASP Clippers. Four price points/price codes - 195, 295, 395, and 500; 8 distinct pens and 3 pencils; 14 different pens if you count both vac-fil and lever; 5 colors; and 3 different "generations" of style, trim, and pattern. They seem to have been made from about 1938 to the early 40s. I've tried to chase only examples in green.
Starting with "generation" or type:
1. Straight sided cap and barrel, faceted jewel on both cap and barrel/blind cap
2. Slightly tapered cap and barrel, shallow dome metal jewel on cap only. Type 2 vac-fil can be found with the same groups of 4 narrow clear stripes as Type 1 and with wide clear stripes.
3. Different pattern to the plastic - wide black or clear stripe and a black plastic cap jewel. David has a pocket knife in type 3 plastic. Some here have claimed to have examples with black jewel on type 2 plastic, but no pictures have been posted.
195 Standard - approx 5" length, .4" barrel diameter
195 Ladies - 4.5" length, .4" diameter
295 Standard - 5", .45"
295 Ladies - 4.5", .45"
395/500 Standard - 5", .45"
395/500 Large - 5 1/8", .51"
Color: black, grey, brown, green, plus the addition of blue in generation/type 3. The "Large" pen was not made in black.
From l-r:
(1) 195 thin vac-fil Standard with Junior nib,
(2) 195 thin lever fill Standard with 4 nib,
(3) 195 thin Ladies lever fill with 4 nib (not made in vac-fil),
(4) 295 full size Standard vac-fil with 6 nib,
(5) 295 full size Standard lever fill with 6 nib,
(6) (gap in photo - don't have example) 295 full size diameter vac-fil Ladies with 6 nib (not made in lever fill),
(7-8) 395 Standard with monotone 7 nib,
(9-10) 500 deluxe Standard with wide cap band and two-tone 7 nib.
(11-12) 395 Large with 7 nib
(13-14) 500 deluxe Large with wide cap band and two-tone 7 nib.
1. Late type 2 vac-fil with wide clear barrel stripes
2. Ladies size type 2 pencil. Note the "cap band" is on the barrel.
3. Type 1 Standard size pencil, 1.1mm lead.
4. Type 2 Standard size pencil, .9mm lead. Note that type 2 has a longer, skinnier tip, a different barrel taper, and different cap/barrel lengths than type 2 (but same overall length). I have a pencil with a type 1 cap and a type 2 barrel; the result is about a 1/4" shorter.
5. Deluxe pencil.
6. Type 3 thin Ladies lever fill pen with 4 nib.
7. Type 3 pencil (in blue).

This picture, snagged from a recent ebay lot, is the only stickered example I've seen.
