Hi. I'm hoping you experts can help me! My Son is 8 and has been collecting vacuums since he was 3. We recently purchased a Singer Compact Model 151. We love getting these old vacs and finding out about them, maybe taking them apart and reassembling them. The trouble with this one is, we can find absolutely zero info about it. All we know is what's on the label, which is Singer Model 151, Made in Italy. Can anyone shed any light at all on this lovely little thing? Pics coming soon when compressed, Son desperate to get the quest underway! Thanks in advance.
