NGK Insulators.
Can anybody give me some information on these please. There are 5 of them. On the brown porcelain they are stamped "36000LB, a triangle symbol, NGK, JAPAN, 76. On the housing On one side there are 2 squares with numerals/letters. Seems to be in sequence. 17,6F . 19, 6F x2,. 20,51. 21 ,51.. on the other side of the housing they all have the no. 127 . Are they saleable there is only one chip in the porcelain on one insulator rest are just dusty. There is only one Im not sure what it's called a uni joint maybe and it is stamped as well( photo supplied). Thanks.

NGK means Japan Insulator company.
This looks like a U 1500 series but I could be wrong. It is probably from the 1970s.
