The shutter has the small wheel at the top for adjust speed.
The settings range from 1 to 200. Don't know the actual speed but the difference between settings seems to be proportional to their difference. It is labeled Anastigmat Trioplan with a focal length of 13.5 cm. 

Alan, this is what the Lens Vade Mecum has to say:
Trioplan f4.5 for rollfilm and Klapp cameras, also in longer foci, for portraiture. It may not always be named, eg as in B.J.A. 1928, p331 where it is just Meyer f4.5 but Trioplan is likely. 

And:
This was a triplet type lens and was 'new' in the Amateur Photo. 16/03/1914. (Q13, Mey012). It was made for cine and portraiture in the larger sizes. Coverage was 40° or up to 65° stopped down.This was a long lived Meyer trade name. [There was a tradition alive in Germany that Roeschlein was one of the designers involved and he then moved to J. Schneider efore setting up on his own.]
Based on all this and what Richard said about the shutter, it would be pre 1930 and thus uncoated and probably wouldn't cover 4x5 unless well stopped down.
