X. 4425 X. 8770 X. 5970 Would you please send to WW. 2 doz. of the latest porcelain cleanable plugs - for New PhantomCodename for PHANTOM I and Goshawk. The doz. we have here are the old-fashioned Lodge mica plugs. If you find the cleanable ones unsuitable for the New PhantomCodename for PHANTOM I or Goshawk, send those with porcelain insulation as at present on the New PhantomCodename for PHANTOM I. This type of plug is just possibly cleanable without detaching it. RA SEE ORIGINAL FOR SKTECH. | ||
