Another early version of the Modell 27 / W28. It has a lot of features in common with the “Modell 26”. In fact I can only find one reall difference: the slots are omited.
This version has the same metal upper and lower housing, with the S&H logo on the back. The dial is a V.sa sch 90 a with enamel (porcelain) number ring and nickel plated brass finger wheel. Please note the circles around the numbers.
As mentioned, there are no vertical slots near in the lower housing. The partition between the bells and electronic components is straight and not bent.
Inside the extra terminal W2, near the rear, close to the cord retaining bracket, is omited. And the bracket is of the small type.
The base plate has the orange/red lettering, typical of Siemens products, with the letter L for the production year 1930.
But the most interesting feature, I think, of this particular specimen, is the round bolt on the handset rest. The far majority of have a hexagonal bolt.
Unfortunately I there was an ill fitting replacement bolt when I got this telephone.
I replaced it with an newer one that was on a Siemens magneto phone from the 1950s. The original one was brass, painted black, as can be seen on my Modell 26.
And of course there is a diagram on the bottom of the base plate, reading Vsa Ms 54S65.
