@revorge

Doh, should have figured that out by myself, but just quickly referenced the pictures when trying to date them. Thanks.

 

@revorge
The number 5358 is also correct.
December 30th,1985 was a Monday.
And December 31,1985 was a Tuesday.
The incomplete 53rd calendar week began in 1985 on December 30th and ended on December 31st.
Your Hipolito with the number 5358 was manufactured on December 30 1985 or December 31,1985.

Thank you for showing this rare number
Regards Reinhard

 

I have a learning disability that affects processing numbers. I’ve read through this post and I’m just not sure I’m dating it right. My lantern is an Aida Petromax 500cp. Code on bottom of fuel tank is 3535. Is that 1953, 35 week?

 

I think week 35 1963 Friday.

 

Thank you so much!

 

Hi Everyone,
Received today my latest acquisition, a Hipolito 502.
The number stamped on the bottom reads 2068, which, from reading this page, I decoded as week 20 (May?) 1986, happy to be corrected if wrong.
Will post in the Reference Gallery once I've taken some pictures.
