Aging

I belong to a group on Ravelry for Leclerc loom owners.  One of the fun things people do is post photos of their looms in an effort to decipher when they were made. 

My loom has a serial number but I think it’s a fairly early model and doesn’t seem to indicate the year.  From the style of decal I’ve decided it is probably from somewhere around 1945-1955.   Why?  Because by 1956 they were including the year.  Since mine doesn’t have a year, I think it must pre-date 1956.
The number isn’t easy to see.  I finally found it to the left of the treadles on the cross piece that holds the treadles.  A light aimed sideways on revealed the date.   The imprint says F-36-11215.
