Check eBay and buy a used meter. I've got a GE (yes, GE) meter from the 1960s or thereabouts that I use with my meterless cameras. I bought it for $15 or less, including postage, and it works fine. If you want to stick with the "authentic Soviet" theme for the camera, look for a Leningrad or Sverdlovsk meter; several models in both lines are available. If you buy used, though, be sure to verify with the seller that it works. This is particularly true of older selenium meters, which tend to die after a decade or two.
