1941 Goeland JOS original head lamp shell

The 1941 Goeland that I have been restoring – a process involving bringing it back to its original condition as much as possible – had a JOS head and tail lamps that were incomplete.  The head lamp was missing its internal parts, with only the pretty aluminum shell remaining, while the rear lamp had still had its “guts”, but was missing the reflectors.  I was fortunate to find a replacement set recently on eBay.

And, I still have some money in my bank account!  This replacement set probably dates to the late 40’s or early 50’s.  I decided to harvest the “guts” of the replacement head lamp and put it into the original shell, which still has some of its red highlighting visible on the JOS starburst logo, as you can make out below:

It was very easy to remove the lens and electrical internals and transfer them to the original shell:

JOS lamps are sought after by restorers and collectors, but I haven’t found much information about the company.

The replacement tail lamp was not an exact match.  However, the length is about right, so I will remove the old “guts” of the rear lamp, and probably not even need to drill any new holes in the fenders.

The JOS replacement lamp has some interesting markings:  Agre’e’ T.P. C 89.

The reflector is cracked, but the rest of the lamp appears fine.

I look forward to getting these replacement lamps installed and functioning, using the Radios Z 27 dynamo that is original to this Goeland, shown above.  Setting up dynamo wiring can test one’s OCD levels and related need for counseling.  Below and above is a nice and professional looking wiring job, from the original bike.

I’ll try to follow this example when I rewire the system. After that, a little mental health therapy may be in order!
