These genuine vintage parts came to us as part of a lot of surplus stock from a large ‘Milspec’ type Co. Having been in storage for many years we have classified them as ‘new other’. However they are ‘as new’ stored with us still in the Maret S.A. boxes in which they were originally supplied. Having been manufactured in 1981 there seems to be nothing on the internet when searching the above part no’s. If anyone has any more information we would be grateful to receive it, we can only guess that they were used in the electronics field or maybe to do with watchmaking, optics or lasers.
