Thanx to Jobers Bersales, some Cebu archival images (scans) from the Ahlborn Collection was made available to me. Part of the collection are black and white images of Oslob Church, the mortuary chapel and the kumbento.
The kumbento photo shows the back, as seen from the nave, with its intact lower walls and, probably, tabique pampango upper walling. Compare this with the fourth image in my kumbento post and you can see very well the changes that have been implemented. Take note of the hollow block and new window in the lower part as well sa the cemented portions of the upper part. While the sliding capiz windows are still as is, the back windows, as seen in the sixth image has already been changed. Do note that after the fire of march 2008, the kumbento was razed to the ground.
The mortuary chapel located infront of the church is still existing until now. However, comparing the archival photo and the current structure, much has changed. The old image still has the original tejas (tiles) roofing, ableit, in bad condition, and the four walls the present one only has the facade and finials present.
This photo is particularly interesting. Here, the pyramidal dome is still being constructed. Note that the church also got burned in 1955, due to unknown reasons, and here, about 10 years later, it is still not finished. You can see the finished dome in this post that existed prior to the March 2008 fire.
