Gearbox identification

[phil23fair]

I have got an Italian ratio Li150 gearbox of unknown provenance where every gear and the Xmas tree is marked with a hand etched letter J about 3mm high which has a little box etched around it. Anybody got any ideas if this is original or one of the recent remade ones?

Sounds like a Series 1 or 2 I believe. Early stuff had the "J" (actually an I but looks like a J).

Usually cast though, not etched, a picture might help.

I don't know how to post photos but if you look at ebay item 171640785871 the second gear in the second photo is marked the same. From replies I have had on the LCGB website it appparently is quite a common marking on early gearboxes especially Li150s

Yep, that's what I meant by cast in, if it looks like that then probably genuine.

You could also use the gear box identification chart , like the one in Sticky's book, and a vernier to take some measurements.

Not the cast Innocenti logo. The second photo, bottom left gear. The etched symbol is on the gear tooth at about 2 o'clock

Yes those are Innocenti.


It's anybody's guess as to why it was engraved on to the gear. If I had to make a guess I'd say it was a production run thing or the guy who had the stamp tool took it home with him the day before. Who knows?

I've never seen or noticed that before

Thanks for your responses. It's going in my TS1 today

Someone has been counting the teeth ( i guess his name was Jim) He has marked a tooth to aid the count. I do it with a felt pen.
