Hello Andy!
I'm currently fighting with clergets... and to tell you the truth I'm little frustrated. Some parts turned out to be impossible for casting (push rods with fastenings and a few little things). I didn't want to simplify anything and kept maximum reality, so I had to prepare it once again. Now I see, it took ma almost one month...
It's the reason of this hugh delay. I'll prepare BrI if only finish Clergets. I'm sorry that it take so long, but I don't want to simplify my engines. Nevertheless I need to consider if it makes any sense: usually when engine is ready, nobody buys it, because models are ready for a long time - last time engines preparing takes me about year...
All the best, Lukasz
