Factory Codes


1. Prior to ESB 32B Backs:
No Factory Codes present.

2. 32B – 48 Backs:
Factory Codes can be present (in several places)
K (“Kader” of Hong Kong)
U (“Unitoys” of Hong Kong)

TW (Taiwan,only on vehicles?)
TC (Taiwan,only on vehicles?)

HN (Hong Kong, Smile)

MC (Macau, only on vehicles???)

So the first letter describes the location in the ROTJ area: T=Taiwan, M=Macau and H=Hong Kong, that is for sure.
The second letter is the factory code.


Here is a little guide to spot those factories regarding the punch. In general Kader, Unitoys and Smile have different punches to their cardbacks.

On ESB 41D/E we have following pairs:

Compared to ROTJ 65A:

In some cases it is difficult to say for sure. Most factories have their “headquarter” in Hong Kong. But some QC Samples show that these are additionally marked with “Macau”, whilst the vendors were/are located in HK. It is also known that round 1983 the HK factories tried to expand into China. The personnel costs were much cheaper there. So many vendors had their “headquarter” still in Hong Kong, but their plants were in China! What does that mean for the figures Coos and the cardback writings? We can asume for now that i.e. Kader (located in HK) produced some of the “raised bar China” figures and the cardbacks say: “Made in China”. I guess G.M. also lost overview pretty fast on a booming plastic industry in the beginnign of the 80s.

Many 65A “HG” have a “Made in Hong Kong” sticker covering printed “China”:
