1st. stamp is probably #411, Flat Plate (18.5mm-19mm x 22mm for stamp design), single line watermark, Perforation 8-1/2. Straight Edge to Straight edge should measure 21.5mm at all points top to bottom. If it is perf. 8-1/2, can only be #411
2nd. stamp appears to be a type II. Appears to be Perforation 10 vert. Could be #454 or #491. #454: single line watermark, rotary press w/design measuring 19.5mm x 22mm or 18.5-19mm x 22.5mm depending upon how the plate was used on the press, straight edge to straight edge measuring 24.5mm-25.0mm along all points top to bottom. #491: unwatermarked, all other parameters same as for #454
Probably #454. #491 is more scarce.
