Ever hear of GOST? I bet some of the LG model numbers are ex Soviet "State Committee" designs adopted for production. As JSC Plasma and the company in Ukraine have a few overlapping models. So some GOST standards specified exact hardware, others specified the functionality and production quality and it was up to competing design bureaus and manufacturing plants to meet the goal however they could.
I've seen pictures of an ophthalmic Argon system that basically was a Nidek clone, right down to a very similar tube to the SP glass Argon. I'm not calling it a copy, as we all know that making the plasma tube was not that easy a task, even if you had one to look at.
A technical standard would often include sample or example plans for the device as a state standard. If you made it to the plans you called it a LG-xxx model, if you modified it, you either applied for another model number or re-labeled it.
Russian: ГОСТ , Is now Euro-Asian Council for Standardization, Metrology and Certification (EASC), See WIKI for a really good explanation.
