Refinishing fir to match existing finished trim from 1929
We recently renovated the basement of our 1929 home. We now have a staircase and beam (see first two photos) to refinish. We would like them to match the finish of the fir on the main level of the house (see next two photos). Does anyone know if fir was finished in those days by simply varnishing, or would there have been a stain used as well, to bring out the rich red tones?
