Alt-Augsburg #3

This cache leads you on a walk through the northern part of the Old Town of Augsburg to some places from which there are still photos from longest past times.

Some views have changed only a little. However, many are to be recognised hardly or no more at all.

The walk begins in the "Jakober Vorstadt" (Jakob suburb) and ends after about 2.6 km near the starting point.

Best of all you come by public means of transportation or by bike. The starting point and the final of the cache are near the stops "Klinik Vinzentinum" (bus line 35), "Barfüßerbrücke" or "Pilgerhausstraße" (tram line 1).

Task

At each stage of this cache you must find out which of the following historical photos has been taken from this place.
Assign the figure of the photo to the letter (A...H) of the respective station. With it you can than calculate the co-ordinates of the subsequent stages and of the final.

In order to make it not too easy, there are a few photos more, than stages!

At some stages you must answer an additional question and find additional solution figures (X, Y) which are necessary to calculate the co-ordinates of the subsequent stages and  the final.

That the page representation is optimum, you should print the listing via [print... > without logs]. Page adjustment: Scaling 100%. Page margins: top, left, right = 5 mm, bottom = 13 mm.

Waypoints:

Stage 01:  N48° 22.324' E10° 54.083'               A =
This is only the start position! There is still no photo!
From here go SSE (south south east) through the lanes (Am Rößlebad) and find yourself the place from where one of the historical photos (A) was taken. The view has changed only marginally.  
Additional question:                                                                                    X =
Which house number (X) carries the house which is to be seen in the left border of the photo, today?   

Stage 02:  N48° 22.(3*A)A' E10° 53.(X+2)(X+1)X'    B =
 

Stage 03:  N48° 22.3(B*10)' E10° 53.(B*2)(B*10)'   C =

 
Stage 04:  N48° 22.(132*C)' E10° 53.(B*20)2'       D =
Hint: On the corresponding historical photo you will see a striking building. This building does not exist anymore.
Additional question:                                                                                   Y =
Near the former location of this building search a stone plaque (in the first floor of a house wall) which reminds of the missing building. Which year was this building torn off? Note the comlete annual number (Y).  

Stage 05:  N48° 22.(Y-1357)' E10° 53.(Y-1153)'     E =
