Pionierul Constructor

Pionierul Constructor was a simple constructional system. It was made in Romania in the 1970s. There appears tobe a little discrepancy in hole spacing (12.8mm and 18.5mm) between some sets, which is why there are two entries from the database noted below.

Comments
From a manual with a line drawing of Lorry on its cover. JOC MECANO from same Metaloglobus firm, features same Lorry model, & also has multicolour parts, but its hole pitch is 12.5 against a reported 12.8 for this system.

The MCS document for this system is shown below. It can also be downloaded to your computer if desired here

Comments
From Tehnometalica firm with B'down Truck on lid & manual. Hole pitch aside parts may be similar to PIONIERUL CONSTRUCTOR [a] but some differ including 7 holes Sector Plate(s), & they are not multicoloured. compare with JOC MECANO parts. *¹In Set 2. *²Up to 4.5 in some parts.
