2, Copper ML-tanks. 2 photos

Here are two of my copper ML., tanks, the smaller one probably dates from the late 1920s, the larger one is from the 1930s.

The small tank is not deep enough to take a pump, so a filler/preesure cap is fitted, Jeff.

 

Here is the larger copper Tilley ML93 fount from the mid to late 1930's, in an oak Veritas woodblock that was used for a centre draft wick lamp.

Sometimes wick centre draft or side draft mantle lamps were fitted into these blocks.

The globe is a Pyrex glass gas globe.

 

Here is the smaller copper tank in a tall oak stand.

This gallery has threaded bolts and threaded apertures, instead of bolts and springs to hold the globe.

The globe is a rather old etched gas globe.

 

All of the copper ML., tanks which I have had and I have had at least 20, have been designed for the XN., control cock.

So in my opinion, all copper tanks must be pre-1939/40, as that was when Tilley changed to the GF., control cock.

They do turn up with different sizes and shapes of riser tubes, (that's what the control cock screws into).

Tilley continued to make the brass ML., tank after 1939/40, so many of the brass ML., tanks which turn up are designed for the GF., control cock only.

I have yet to see a brass ML., tank which has more than the mere rim of a riser tube.

All of the above information is my opinion, which is based on experience and common sense.

There is Tilley paperwork which shows that the change over from the XN., control cock to the GF., control cock took place in 1939/40, Jeff.

 

Here is a copper ML., in another wooden stand, Jeff.

 

hi, can you share some knowage about the difference size of tank ML & KL? brass KL tank it too big for Jacobean right?

 

Hello, the first two images which show the two copper ML., tanks clearly show the difference in their sizes.
Brass ML., & KL., tanks are the same, but from about 1950 the design of the tanks changed and those tanks will not fit a Jacobean bowl, the tanks from 1950 onwards were painted cream and the tops of those tanks were highly polished and lacquered and the link below shows my example, many tanks which turn up these days have had the paint removed.

1961, KL.,80.

 

thanks @JEFF JOHNSON that it mean. the tank fit a Jacobean stand should be early 1950. thank agian

 

Hello, you are welcome and yes, a pre 1950 tank is required for the Jacobean bowl.

The first link below shows one of my Jacobean lamps and it has a brass tank, but it still has the original dark lacquered finish, the second link shows relevant information.
