It's interesting that camera prices start to drop in relative terms with much greater production volumes in the 1930's but they stayed expensive until the 1960's in relation to average wages.

I haven't a pre-WWII reference to Ikomat cameras in the UK, the name wasn't used here however it does appear that name Ikomat is used in the US instead of Ikonta even on top models. Maybe there was a trademark issue. This happend to Exacta with the Varex models which were sold as VX in the US.

The TLR Ikoflex was sold as an Ikomat as well in the US.
