After discussion with this supplier, here's the skinny:
It is a small 2 man operation so output can expected to be limited. I look forward to visiting in the near future.
The Tigers shown are not their production but reworked HL 1/6 & 1/8 models customers have sent them for mods / rebuilds. The only models currently available are their new 1/6 Pz III H. Underway is a 1/16 King Tiger which will be offered soon, but in limited quantities, afterwards is a 1/16 Tiger followed by a 1/6 Tiger.
On conversion kits, currently offer 1/16 lower hulls for HL Challenger & M1 Abrams; also a dual differential gearbox. Other mods offered, mostly for HL conversions.
I received a number of photos that look nice; will post more later for reference.
