window crank

Hi,

On the parts shown in the attached picture, the name on the part is

Entry Gard (Truth)

there are 5 digit numbers on each of the individual parts:

The main hub with the gear assembly is #45179

the other numbers on the individual connected parts are: #40753, #20810
#20545, # 31538

On the bottom of the main part was U.S. Pat. 4.241.541 Pat. 1982

Thank you!!

Same question just to verify. US Patent 4.241.541 gives Can patent and then says pat 1982. Front says 40471, made in USA, have picture of a house with Truth written under it. Shorter arm has 30842r and 20810 on it. These appear to have been brown, brass, or bronze originally. I need both left and right swing controllers. Thank you.
