Description

This is unique example of strict Soviet Union disco laser LSU-1 made in Ukraine, "Gasotron" factory. It was made on HeNe tube ILGN-203 in 1989 year when already exists a diode lasers. Don't know why so technical resolution))) In this example laser tube is leaked, mechanic part working,  but I could get a fully working example - just need 2-4x times more money if you wish to request. Very unique device!
